Symbol

Note

RSET

An RS resistor between this pin and GND fixes the power limiting threshold

VIN

Input voltage

PWM

A PWM signal can be provided through this pin to turn-ON/OFF the power switch

If PWM function is not used it is suggested to connect this pin to EN or VIN

Monitor/fault Power monitor signal, fault signal

CSET

A CS capacitor between this pin and GND sets the auto-retry delay

Enable

Enable pin (device active when EN=high)

VOUT

Output pin

Rdelay

An RD resistor connected between this pin and GND sets the power limit masking time. Do not

connect this pin directly to GND
