The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.
This document describes how to design a 3-phase (106 ~ 848 VAC) power supply with the UC3845B PWM driver and the new STC04IE170 ESBT as main switch. It is associated with the release of the STEVAL-IPB001V1 demo board.
The MAX15020 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX15020 PWM step-down regulator IC with an integrated high-side switch. The MAX15020 is equipped with a reference input for the feedback error amplifier, allowing dynamic output-voltage programming. The MAX15020 EV kit operates over a wide input-voltage range of 7.5 V to 40 V and provides up to 2A.
The BD70522GUL-EVK-101 evaluation board is a power supply solution designed for battery powered devices. 180nA quiescent current and ULP (Ultra Low Power) mode enable excellent light load efficiency at 10µA load, extending battery life, while output currents up to 500mA are supported. Users can select from among 9 preset output voltages via the VSEL pin. And when the input voltage gets close to the output voltage, the IC enters 100% ON mode that stops switching operation.
The STEVAL-ISA180V1 evaluation board implements a wide mains range flyback isolated converter (12 V - 0.6 A), developed for general purpose applications.
The TPS62823EVM-005 evaluation module (EVM) facilitates the evaluation of the TPS62823 3-A, step-down converter with DCS-Control in a 2-mm by 1.5-mm QFN package. The EVM outputs a 1.8-V output voltage with 1% accuracy from input voltages between 2.4V and 5.5V with a maximum solution height of 1 mm.
The TLV62569EVM-884 evaluation module (EVM) is designed to help the user easily evaluate and test the operation and functionality of the TLV62569PDDC. The EVM converts a 2.5-V to 5.5-V input voltage to a regulated output voltage of 1.8V at up to 2 A output current.
The LM73605EVM-5V-400K evaluation module (EVM) is a fully assembled and tested circuit for evaluating the LM73605 synchronous step-down voltage converter. The EVM operates from 6V to 36V input and provides a 5V output voltage with 5A maximum load current.
The LMS3655xQEVM is specifically designed for automotive and high-performance industrial applications, providing an output voltage of 5 V, 3.3 V, or an adjustable output at a continuous load of 5.5-A.
The RT7247A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 18V input supply. The RT7247A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors.
