G5138PK - Digital Green-Mode QR Primary-Side PWM Power Switch

Download the G5138PK datasheet PDF. This datasheet also covers the G5138PA variant, as both devices belong to the same digital green-mode qr primary-side pwm power switch family and are provided as variant models within a single manufacturer datasheet.

Description

The G5138P is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies.

Features

  • while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The -K version can operate at peak power mode with momentary peak power higher than the maximum continuous output power without design cost and size increase. The G5138P removes the need for secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop compensation components while maintaining stability over all operating conditi.
