General Description
The FA3641P(N) and FA3647P(N) are the PWM type switching power supply control ICs that can directly drive power MOSFET.
These ICs use a CMOS device with high dielectric strength (30V) to implement low power consumption.
Key Features
- Uses a newly developed CMOS process with high dielectric strength (30V) for implementing low power consumption.
- Standby current of 2µA or less (at Vcc=14V), and operating current of 1.9mA (typ. ).
- Automatically reduces the oscillation frequency to suppress loss of the power supply in light load mode.
- Overvoltage protection function detecting Vcc voltage.
- A drive circuit for connecting a power MOSFET directly.
- Output peak current: Source curre.
