FA13842 - Brand New FUJITSU LEDs, Lamps - Lenses
-
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. They can drive a power MOSFET directly, allowing for high-performance and compact power supply designs with minimal external components.
Specifications and 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 UC384XApplication Scenarios
The FA13842 current mode control ICs can be used in various applications such as off-line power supplies and DC-to-DC converters. Due to their low power dissipation and high efficiency, they are particularly suitable for power supply designs where minimal external components are desired.
