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.

Power Management > Power Factor Correction ADP1047-300-EVALZ: 300W PFC, 385V Out, 85 ~ 265V in Manufacturer: Analog Devices Inc.

This evaluation board features the ADP1047 in a typical AC/DC switching power supply in a boost power factor correction (PFC) topology. The circuit is designed to provide a rated load of 385V/300W from an AC input voltage source of 85 VRMS to 265 VRMS AC. The ADP1047 provides functions all the functions necessary for active PFC circuit plus accurate AC power metering. It achieves near-unity power…
