Current Mode PWM Controller

Description

Features

Applications

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.

Protection

circuitry

includes built under voltage lockout and

current limiting.

The KA384x 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.

Operating Frequency Up to 500KHz

Switching Mode Power Supplies

Power Converters

Under Voltage Lockout With Hysteresis

Low Star-up and Operating Current

High Current Totem Pole Output
