AS998 Product details

Description

The AS998/AS998A is an IC intended for use as a PWM controller for switch mode power supplies.

The device is particularly suited as a primary side controller for adapter, printer, peripheral, mobile chargers and desktop auxiliary power supplies.

Features

such as fixed internal oscillator, internal ramp compensation and current filters all reduce the external support components. Features.
Low start-up current 64 µA (Typ) Low running current 2 mA (Typ) Low power light load mode Low power standby when OV is activated Extended commercial operating temperature range: 0 to 105°C On-board fixed frequency oscillator 100 kHz (Typ) Frequency rando.
