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, accomplishing high-speed switching with rising time tr = 80 ns (typ) and falling time t f = 40 ns (typ) at 20 V swing.
Functions • • • • • • Reference voltage circuit Triangular waveform oscillation circuit PWM comparator circuit Low-input malfunction protection circuit Output drive circuit Soft start and quick shut down Features • High s...
