MAXIM Manuals

The MAX5003 high-voltage switching power-supply controller has all the features and building blocks needed for a cost-effective flyback and forward voltage-mode control converter. This device can be used to design both isolated and nonisolated power supplies with multiple output voltages that operate from a wide range of voltage sources. It includes a high-voltage internal start-up circuit that operates from a wide 11V to 110V input range. The MAX5003 drives an external N-channel power MOSFET and has a current-sense pin that detects overcurrent conditions and turns off the power switch when the current-limit threshold is exceeded. The choice of external power MOSFET and other external components determines output voltage and power. The MAX5003 offers some distinctive advantages: soft-start, undervoltage lockout, external frequency synchronization, and fast input voltage feed-forward. The device is designed to operate at up to 300kHz switching frequency. This allows use of miniature magnetic components and low-profile capacitors. Undervoltage lockout, soft-start, switching frequency, maximum duty cycle, and overcurrent protection limit are all adjustable using a minimum number of external components. In systems with multiple controllers, the MAX5003 can be externally synchronized to operate.

The MAX500 is a quad, 8-bit, voltage-output digital-to-analog converter (DAC) with a cascadable serial interface. The IC includes four output buffer amplifiers and input logic for an easy-to-use, two- or three-wire serial interface. In a system with several MAX500s, only one serial data line is required to load all the DACs by cascading them. The MAX500 contains double-buffered logic and a 10-bit shift register that allows all four DACs to be updated simultaneously using one control signal. There are three reference inputs so the range of two of the DACs can be independently set while the other two DACs track each other. The MAX500 achieves 8-bit performance over the full operating temperature range without external trimming.

The MAX5012 is a 12-bit, 100Msps digital-to-analog converter (DAC) designed for digital modulation, direct digital synthesis, high-resolution imaging, and arbitrary- waveform-generation applications. This device is pin- for-pin compatible with the AD9712 with significantly improved settling time and glitch-energy performance. The MAX5012 is an ECL-compatible device. It features a fast 13ns settling time and low 15pV-s glitch impulse energy, which results in excellent spurious-free dynamic range characteristics. The MAX5012 is available in a 28-pin plastic DIP or PLCC package in the -40°C to +85°C extended-industrial temperature range.

The MAX5013 is a 12-bit, 100Msps digital-to-analog converter (DAC) designed for digital modulation, direct digital synthesis, high-resolution imaging, and arbitrary-waveform-generation applications. This device is pin-for-pin compatible with the AD9713 with significantly improved settling time and glitch-energy performance. The MAX5013 is a TTL-compatible device. It features a fast 13ns settling time and low 15pV-s glitch impulse energy, which results in excellent spurious-free dynamic-range characteristics. The MAX5013 is available in a 28-pin plastic DIP or PLCC package, in the -40°C to +85°C extended-industrial temperature range.

The MAX5014/MAX5015 integrate all the building blocks necessary for implementing DC-DC fixed-frequency isolated power supplies. These devices are current-mode controllers with an integrated high-voltage startup circuit suitable for isolated telecom/industrial voltage range power supplies. Current-mode control with leading-edge blanking simplifies control-loop design and internal ramp compensation circuitry stabilizes the current loop when operating at duty cycles above 50% (MAX5014). The MAX5014 allows 85% operating duty cycle and could be used to implement flyback converters, whereas the MAX5015 limits the operating duty cycle to less than 50% and can be used in single-ended forward converters. A high-voltage startup circuit allows these devices to draw power directly from the 18V to 110V input supply during startup. The switching frequency is internally trimmed to 275kHz ±10%, thus reducing magnetics and filter component costs. The MAX5014/MAX5015 are available in 8-pin SO packages. An evaluation kit (MAX5015EVKIT) is also available.

MAX5018 is a 8-bit digital to analog converter from Texas Instruments, which can accept video data at 165Msps or 275Msps. It has complete video controls (sync, blank, reference white (force high), and bright), and can directly drive doubly terminated 50Ω or 75Ω loads to standard composite video levels. Standard setup level is 7.5IRE. MAX5018 is pin compatible with the HDAC10180 and the TDC1018, with improved performance. The product contains data and control input registers, video control logic, reference buffer, and current switches. Two performance grades of the MAX5018 are available. Both are packaged in a 24-pin PDIP in the -20°C to +85°C industrial temperature range.

The MAX5025-MAX5028 are constant-frequency, pulse-width modulating (PWM), low-noise boost converters designed for low-voltage systems that require locally generated high voltage. They are capable of generating low-noise, high output voltages required for varactor diode biasing in TV tuners, set-top boxes, and PCI cable modems. The MAX5025-MAX5028 operate from as low as 3V and switch at 500kHz. The constant-frequency, current-mode PWM architecture provides for low output noise that is easy to filter. A 40V lateral DMOS device is used as the internal power switch, making the devices ideal for boost converters up to 36V. The MAX5025/MAX5026 adjustable versions require the use of external feedback resistors to set the output voltage. The MAX5027/MAX5028 offer a fixed 30V output. These devices are available in a small, 6-pin SOT23 package.

The MAX5033 is a high-voltage step-down DC-DC converter from Texas Instruments. It has a maximum input voltage of 76V and can output 3.3V, 5V, or 12V at up to 500mA.
