Download the CS5126 datasheet PDF. This datasheet also covers the CS5124 variant, as both devices belong to the same integrated current mode pwm controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

PACKAGE PIN # CS5124 1 2 3 4 5 CS5126 1

3 2 4 5 Pin VCC BIAS SYNC UVLO SS VFB VCC Power Input Pin.

VCC Clamp Output Pin.

channel MOSFET that in turn regulates Vcc.

This pin is internally clamped at 15 V when the IC is in sleep mode.
