SLUSBN6 –JULY 2013

CURRENT MODE PWM CONTROLLER

Check for Samples: UC1843-DIE

FEATURES

•

Optimized For Off-line and DC-to-DC

Converters

•

Enhanced Load Response Characteristics

Under-Voltage Lockout With Hysteresis

•

Low Start-Up Current

Double Pulse Suppression

High Current Totem Pole Output

Low R_OError Amp

Automatic Feed Forward Compensation

Pulse-by-Pulse Current Limiting

DESCRIPTION

The UC1843-DIE provides the necessary features to implement off-line or dc-to-dc fixed frequency current mode

control schemes with a minimal external parts count. Internally implemented circuits include under-voltage

lockout featuring start up current, logic to insure latched operation, a PWM comparator which also provides

current limit control, and a totem pole output stage designed to source or sink high peak current. The output

stage, suitable for driving N-Channel MOSFETs, is low in the off state.

(1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI

web site at www.ti.com.

(2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality

Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room

temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not

warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
