HA16654A Overview
HA16654A, HA16664A Series PWM Controlled Switching Regulator The HA16654A and HA16664A are PWM control switching regulator ICs which drive a power MOSFET at high speed and high frequency. The standby current is limited to as small as 1.5 mA (typ). These devices incorporate totem pole circuits suited for high-speed push-pull operation at the output stage, acplishing high-speed switching with rising time tr = 80 ns...
