The SP7650 is a 3A, 300kHz, synchronous step-down switching regulator from Sipex Corporation. The device has a maximum input voltage of 2.5V to 28V, an output voltage down to 0.8V, and a 3A output capability. It integrates low RDSON power switches, is highly integrated, and has a minimal number of external components. The device operates at a fixed frequency of 300 kHz and has UVLO, overtemperature protection, and short circuit protection.

The LTC ®3423 and LTC3424 are high efficiency, fixed frequency, step-up DC/DC converters that can regulate output voltages as low as 1.5V from a single cell. An applied voltage of at least 2.7V to the VDD pin is required to power the internal control circuitry. The devices include a 0.16Ω N-channel MOSFET switch and a 0.21Ω P-channel synchronous rectifier. The LTC3423 is intended for applications requiring less than 0.75W of output power and the LTC3424 for 1.5W or less. Switching frequencies up to 3MHz are programmed with an external timing resistor and the oscillator can be synchronized to an external clock. Quiescent current is only 38µA in Burst Mode operation, maximizing battery life in portable applications. Burst Mode operation is user controlled and can be enabled by driving the MODE/SYNC pin high. If the MODE/SYNC pin has either a clock or is driven low then the operation is at constant fixed frequency. Other features include a 1µA shutdown, thermal shutdown and current limit. The LTC3423 and LTC3424 are available in the 10-lead MSOP package. For applications requiring an output voltage greater than 2.6V, the LTC3401 and LTC3402 are recommended without the need of a separate voltage for the VDD pin.

This document introduces the features and characteristics of LM3671 step-down DC-DC converter. LM3671 step-down DC-DC converter is designed for power supply low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. The chip provides up to 600mA load current, over the entire input voltage range. There are several different fixed voltage output options available as well as an adjustable output voltage version. The device offers superior features and performance for mobile phones and similar portable systems. Automatic in- telligent switching between PWM low-noise and PFM low- current mode offers improved system control. During PWM mode, the device operates at a fixed-frequency of 2 MHz (typ). Hysteretic PFM mode extends the battery life by re- ducing the quiescent current to 16 µA (typ) during light load and standby operation. Internal synchronous rectification provides high efficiency during PWM mode operation. In shutdown mode, the device turns off and reduces battery consumption to 0.01 µA (typ). The LM3671 is available in SOT23-5 and a tiny 5-bump micro SMD packages in leaded (PB) and lead-free (NO PB) versions. A high switching frequency of 2 MHz (typ) allows use of tiny surface-mount components. Only three external surface-mount components, an inductor and two ceramic capacitors, are required.

VIPer100/100A is a power management IC made using VIPower M0 technology, which integrates an advanced PWM circuit and an optimized high voltage vertical power MOSFET (620V or 700V / 3A). The product features adjustable switching frequency, current mode control, soft start and shutdown control, automatic burst mode operation, internally trimmed zener reference, undervoltage lock-out with hysteresis, integrated start-up supply, over-temperature protection, low standby current, and adjustable current limitation. It is suitable for offline power supplies, providing a secondary power capability of 50W in wide range conditions and 100W in single range or with doubler configuration. It requires around 50% less components compared to a discrete solution.
