Description
Pwm Controlled Switching Regulator
Manufacturer
Renesas Electronics Corporation.
Datasheet
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
V swing.
