General Description

The HY3842D-N/3843D-N/3844D-N/3845D-N, are fixed frequency current mode PWM controller.

They are specially designed for OFF−Line and DC to DC converter applications with a minimal external components.

Internally implemented circuits include a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.

Key Features

Low Start-Up and Operating Current High Current Totem Pole Output Under voltage Lockout With Hysteresis Operating Frequency Up To 500KHz BLOCK.
