Description

GR9235Q  is  integrated  a   high  performance multi-mode  (QR/DCM/Burst)  PWM  converter and a 650V supper junction MOSFET. It could turn  standby  mode  to  green  mode  for  high switching efficiency. It provides functions of low startup  current,  over  current  protection,  over

voltage   protection,   short   circuit   protection, brown  in/out  protection,  and  internal  OTP  to prevent the circuit being damaged.

Application

l PD+QC Charger

l Switching Mode Power Supply
