Product Summary

The AN8090 is an overvoltage protective circuirs built-in switching power supply. The AN8090 enables high-speed control up to 500kHz and has various protective functions for over current , overvolotage, and thermal protection in order to improve reliability of the power supply.

Parametrics

AN8090 absolute maximum ratings: (1)Supply voltage, VCC: 35V; (2)Peak output current, IO: ±2A; (3)Maximum continuous output current, IO: ±0.15A; (4)Power dissipation, PD: 1.5W; (5)Operating ambient temperature, Topr: -30 to +85℃; (6)Storage temperature, Tstg: -55 to +150℃.

Features

AN8090 features: (1)500kHz PWM control frequency and miniaturized; (2)Capable of directly driving the large-capacity MOSFET; (3)Provided with 2-channel overcurrent protective function for positive side and negative side, and intermittent operating function as protection when an over-current state advanced further; (4)Provided with over-voltage protective and over-heat protective functions; (5)Provided with the ON/OFF function to start/stop operating the power supply with external signals and the error amlifier required for secindarry control; (6)16-DIP package for the AN8090 and SONF-20D for the AN8090S.
