FA13842 - CMOS IC(For Switching Power Supply Control)

Description

The FA1384X series are CMOS current mode control ICs for off-line and DC-to-DC converters.

These ICs can reduce start-up circuit loss and are optimum for high efficiency power supplies because of the low power dissipation achieved through changes in the CMOS fabrication process.

Features

  • CMOS process Low-power dissipation Standby current 2µA (max. ), start-up current 30µA (max. ) Pulse-by-pulse current limiting 5V bandgap reference UVLO (Undervoltage lockout) with hysteresis Maximum duty cycle FA13842, 13843: 96% FA13844, 13845: 48%.
  • Pin-for-pin compatible with UC384X Note: Pins are fully compatible, but characteristics are not. When our ICs are applied to a power supply circuit designed for other manuf.
