s 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.
These ICs can drive a power MOSFET directly.
The high-performance, compact power supply can be
designed with minimal external components .
s Features
CMOS process
Low-power dissipation
Standby current 2
A (max.), start-up current 30A (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 manufactures' 384X series, the
characteristics and safety features of the power supply
must be checked.
