LTC3723-1/LTC3723-2

Synchronous Push-Pull

PWM Controllers

DESCRIPTIO

FEATURES

TheLTC^®3723-1/LTC3723-2synchronouspush-pullPWM

controllers provide all of the control and protection func-

tions necessary for compact and highly efficient, isolated

power converters. High integration minimizes external

component count, while preserving design flexibility.

■

High Efficiency Synchronous Push-Pull PWM

■

1.5A Sink, 1A Source Output Drivers

■

Supports Push-Pull, Full-Bridge, Half-Bridge, and

Forward Topologies

■

Adjustable Push-Pull Dead-Time and Synchronous

Timing

The robust push-pull output stages switch at half the

oscillator frequency. Dead-time is independently pro-

grammed with an external resistor. Synchronous rectifier

timing is adjustable to optimize efficiency. A UVLO pro-

gram input provides precise system turn-on and turn off

voltages. The LTC3723-1 features peak current mode

controlwithprogrammableslopecompensationandlead-

ing edge blanking, while the LTC3723-2 employs voltage

mode control with voltage feedforward capability.

■

Adjustable System Undervoltage Lockout and

Hysteresis

■

Adjustable Leading Edge Blanking

■

Low Start-Up and Quiescent Currents

■

Current Mode (LTC3723-1) or Voltage Mode

(LTC3723-2) Operation

■

Single Resistor Slope Compensation

■

V_CCUVLO and 25mA Shunt Regulator

■

Programmable Fixed Frequency Operation to 1MHz

■

50mA Synchronous Output Drivers

The LTC3723-1/LTC3723-2 feature extremely low operat-

ing and start-up currents. Both devices provide reliable

short-circuit and overtemperature protection. The

LTC3723-1/LTC3723-2 are offered in a 16-pin SSOP

package.

■

Soft-Start, Cycle-by-Cycle Current Limiting and

Hiccup Mode Short-Circuit Protection

■

5V, 15mA Low Dropout Regulator

■

Available in 16-Pin SSOP Package
