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 t_r= 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 speed switching: t_r= 80 ns, t_f= 40 ns (typ) when use exernal driver circuit

High frequency operation:

HA16654A (f = 100 kHz to 500 kHz)

HA16664A (f = 100 kHz to 200 kHz)

Low power dissipation : 2 mA max in standby state

5 V reference voltage

•

Low-input malfunction protection (High threshold voltage: 10 V Typ, Low threshold voltage: 8 V

Typ)

•

Adjustable dead band width

Enlarged output pulse width control range (0 to 80%)

Soft start and quick shut down functions

Single output: totem pole
