s Description
FA3630V is a DC-DC converter controller.
This IC can directly drive a Nch/Pch-MOSFET.
This IC is suitable to reduce converter size because it has
many functions in a small package TSSOP.
s Features
• Low input voltage: 2.5V to 6.5V
• 2-channels PWM control: Rail-to-rail output
Output impedance of output stage = 3.5Ω (typ.)
Nch-MOSFET driving (Ch1)
Nch/Pch-MOSFET driving (Ch2)(selected by SEL pin)
• Low power consumption: 0.7mA (typ.)
• ON/OFFcontrol: Standby current= 0.1µA (typ.)
• ±2% high accuracy reference voltage
• Adjustable soft start time and maximum duty cycle
• Adjustable built-in timer latch for short circuit protection
• Wide range of operation frequency: 100kHz to 1MHz
• Package: TSSOP-16 (Thin and small)
s Applications
• Power supply for general equipment
