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
