AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output EVB_RT2856GQW: 3.3V @ 6A, 4.5 ~ 18Vin Manufacturer: Richtek USA Inc.

The RT2856GQW is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 6A output current from a 4.5V to 18V input supply. The RT2856GQW current-mode architecture with externalcompensation allows the transient response to be optimized over a wide range of loads and output capacitors.

AC/DC and DC/DC Conversion > AC/DC SMPS - Single Output RDK-420: 5V @ 2A, 10W, 85 ~ 264V in Manufacturer: Power Integrations

This document is an engineering report describing a 2 A, 5.0 V USB charger utilizing a device from the InnoSwitch-CH family of ICs. This design is intended to show the high power density and efficiency that is possible due to the high level of integration while still providing exceptional performance.

AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output EVB_RT7250BZSP: 3.3V @ 2A, 4 ~ 17Vin Manufacturer: Richtek USA Inc.

The RT7250B is a high efficiency, monolithic synchronous step-down DC/DC converter that operates at 800kHz and delivers up to 2A output current from a 4V to 17V input supply. The RT7250B’s current mode architecture allows the transient response to be optimized.
