WT7520 — Даташит
Datasheet Weltrend Semiconductor WT7520 Микросхемы питания PC Power Supply PWM Supervisor The WT7520 is a pulse–width modulation (PWM) control circuit with complete protection circuits for used in the SMPS (Switched Mode Power Supply).
Подробное описание
It contains various functions, which are Over Voltage Protection, Under Voltage Protection, Power Good Output (PGO), Remote On/Off control and etc. It can minimize external components of switching power supply systems in personal computer. Over Voltage Protection (OVP) monitors 3.3 V, 5 V, 12 V and PT input voltage level. Under Voltage Protection (UVP) monitors 3.3 V, 5 V and 12 V input voltage level. Power Good Output monitors the voltage level of power supply.
