INTELLIGENT VOLTAGE MODE PWM IC

KA3511/D

GENERAL DESCRIPTION

22-DIP-400 / 24-SOP-300

The KA3511/D is a fixed-frequency improved-

performance pulse-width modulation control circuit

with complete housekeeping circuitry for use in the

secondary side of SMPS (Switched mode power

supply). It contains various functions, which are

precision voltage reference, over voltage protection,

under voltage protection, remote on/off control, power

good signal generator and etc.

OVP (Over voltage protection) section

It has OVP functions for +3.3V,+5V,+12V and PT

outputs. The circuit is made up of a comparator with

four detecting inputs and without hysteresis voltage.

Especially, PT (Pin16) is prepared for an extra OVP

input or another protection signal.

ORDERING INFORMATION

Device

KA3511

Package

22 DIP

Operating Temperature

-25°C ~ 85°C

UVP (Under voltage protection) section

KA3511D

It also has UVP functions for +3.3V, +5V, +12V

outputs. The block is made up of a comparator with

three detecting inputs and without hysteresis voltage.

24 SOP

-25°C ~ 85°C

FEATURES

Remote on/off section

•

Complete PWM control and house keeping

circuitry

Remote on/off section is used to control SMPS

externally. If a high signal is supplied to the remote on/

off input, PWM signal becomes a high state and all

secondary outputs are grounded. The remote on/off

signal is transferred with some on-delay and off-delay

time of 8ms, 24ms respectively.

•

Few external components

Precision voltage reference trimmed to 2%

Dual output for push-pull operation

Each output TR for 200mA sink current

Variable duty cycle by dead time control

Soft start capability by using dead time control

Double pulse suppression logic

Precision reference section

The reference voltage trimmed to ± 2%

(4.9V≤Vref≤5.1V)

Over voltage protection for 3.3V / 5V / 12V

Under voltage protection for 3.3V / 5V / 12V

PG (Power good signal generator) section

Power good signal generator is to monitor the voltage

level of power supply for safe operation of a

microprocessor.

One more external input for various protection

(PT)

•

Remote on/off control function (PS-ON)

KA3511 requires few external components to

accomplish a complete housekeeping circuits for

SMPS. The KA3511 is available in a 22-pin dual in-line

package.

Latch function controlled by remote and protection

input

•

Power good signal generator with hysteresis
