■ Description
  The FA7611CP(E) is a bipolar IC containing basic circuit necessary for PWM-type switching power supply control.

■ Features
• Low-voltage operation (VCC = 3.6 to 22V)
• Predrivers: Totem-pole output or open-collector for CH1 and open-collector output for CH2
• Latch-mode short-circuit protection function (no malfunction due to electrical noise)
• soft-start function
• Undervoltage lock-out function
• One capacitor shared for short circuit protection and for soft start to minimize the number of external discrete components

■ Applications
• Battery power supply for portable equipment
