FA531X series series FA531X Bipolar IC For Switching Power Supply Control s Dimensions, mm SOP-8 8 5 FA5310BP(S), FA5314P(S), FA5316P(S) FA5311BP(S), FA5315P(S), FA5317P(S) s

Description

The FA531X series are bipolar ICs for switching power supply control that can drive a power MOSFET. These ICs contain many functions in a small 8-pin package. With these ICs, a high-performance and compact power supply can be created because not many external discrete components are needed. 1 6.05 4 +0.1 –0.05 • Drive circuit for connecting a power MOSFET • Wide operating frequency range (5 to 600kHz) • Pulse-by-pulse overcurrent limiting function • Overload cutoff function (Latch or non-protection mode selectable) • Output ON/OFF control function by external signal • Overvoltage cutoff function in latch mode • Undervoltage malfunction prevention function • Low standby current (90µA typical) • Exclusive choices by circuits (See selection guide on page 25) • 8-pin package (DIP/SOP) ° 0~10 0.4±0.1 1.27±0.2 0.6 DIP-8 8 5 s Applications • Switching power supply for general equipment 1 9.3 1.5 4 6.5 3.0min 4.5max 3.4 0.3 7.6 s Block diagram FA5310BP(S)/FA5311BP(S)/FA5316P(S)/FA5317P(S) 2.54±0.25 0.5±0.1 0~15 ˚ 0~1 5˚ Pin No. 1 2 3 4 5 6 7 8 Pin symbol
