KA3842AM datasheet

Description

The KA3842AM are fixe frequency current-mode PWM controller. They are specially designed for OFF-Line and DC-to-DC converter applications with minimal external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totempole output ideally suited for driving a power MOSFET.

Features

1. Low Start-Up Current

2. Maximum Duty Cycle

3. U/V Lockout With Hysteresis

4. Operating Freguency Up To 500khz
