High Voltage, 1.5A, 500kHz Step-Down Switching Regulators

MAX9030/MAX9031/MAX9032/MAX9034 single/dual/quad comparators are optimized for single-supply applications from +2.5V to +5.5V but can also be oper- ated from dual supplies. These comparators have a 188ns propagation delay and consume 35µA of supply current per comparator over the -40°C to +125°C oper- ating temperature range. The combination of low- power, single-supply operation down to +2.5V, and ultra-small footprint makes these devices ideal for portable applications. The MAX9030 is a low-cost single comparator with shutdown. The MAX9031, MAX9032, and MAX9034 are low-cost single, dual, and quad comparators without shutdown, respectively. The comparators’ 4mV of built- in hysteresis provides noise immunity and prevents oscillations even with a slow-moving input signal. The input common-mode range extends from the negative supply to within 1.1V of the positive supply. The design of the comparator output stage substantially reduces switching current during output transitions, virtually eliminating power-supply glitches. The MAX9030 single comparator with shutdown is avail- able in the space-saving 6-pin SC70 and SOT23 pack- ages. The MAX9031 single comparator is available in tiny 5-pin SC70 and SOT23 packages. The MAX9032 dual comparator is available in 8-pin SOT23 and µMAX pack- ages, and the MAX9034 quad comparator is available in a 14-pin TSSOP package.

The LM2672 series of regulators are monolithic integrated circuits built with a LMDMOS process. These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load current with excellent line and load regulation. These devices are avail- able in fixed output voltages of 3.3V, 5.0V, 12V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation (Patent Nos. 5,382,918 and 5,514,947), fixed frequency oscillator, external shutdown, soft-start, and frequency synchronization. The LM2672 series operates at a switching frequency of 260 kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regu- lators. Because of its very high efficiency (>90%), the cop- per traces on the printed circuit board are the only heat sinking needed. A family of standard inductors for use with the LM2672 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies using these advanced ICs. Also included in the datasheet are selector guides for diodes and capacitors designed to work in switch-mode power supplies. Other features include a guaranteed ±1.5% tolerance on output voltage within specified input vo

The IL74/ ILD74/ ILQ74 is an optically coupled pair with a GaAIAs infrared LED and a silicon NPN photo-transistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output.

The LTC3703 is a synchronous step-down switching regulator controller that can directly step down voltages from up to 100V, making it ideal for telecom and automotive applications. It drives external N-channel MOSFETs using a constant frequency (up to 600kHz), voltage mode architecture. A precise internal reference provides 1% DC accuracy. It has a high bandwidth error amplifier and patented line feed-forward compensation for fast line and load transient response. The LTC3703 has strong 1Ω gate drivers for higher current applications. The operating frequency is user programmable from 100kHz to 600kHz and can be synchronized to an external clock for noise-sensitive applications. Current limit is programmable with an external resistor and utilizes the voltage drop across the synchronous MOSFET to eliminate the need for a current sense resistor. For applications requiring up to 60V operation with logic-level MOSFETs, refer to the LTC3703-5 data sheet.

The USBN9603/4 are integrated USB Node controllers with enhanced DMA support. They are compatible with USB specification versions 1.0 and 1.1, and are advanced versions of the USBN9602. The devices integrate the required USB transceiver, a 3.3V regulator, a Serial Interface Engine (SIE), USB endpoint (EP) FIFOs, a versatile 8-bit parallel interface, a clock generator, and a MICROWIRE/PLUS™ interface. Seven endpoint pipes are supported: one for the mandatory control endpoint and six to support interrupt, bulk, and isochronous endpoints. Each endpoint pipe has a dedicated FIFO, 8 bytes for the control endpoint and 64 bytes for the other endpoints. The 8-bit parallel interface supports multiplexed and non-multiplexed style CPU address/data buses. A programmable interrupt output scheme allows device configuration for different interrupt signaling requirements.
