LTC3721-1

Push-Pull PWM Controller

DESCRIPTIO

FEATURES

The LTC^®3721-1 push-pull PWM controller provides all of

the control and protection functions necessary for com-

pact and highly efficient, isolated power converters. High

integration minimizes external component count, while

preserving design flexibility.

■

High Efficiency Push-Pull PWM

■

1.5A Sink, 1A Source Output Drivers

■

Adjustable Push-Pull Dead-Time

■

Adjustable System Undervoltage Lockout and

Hysteresis

■

Adjustable Leading Edge Blanking

The robust push-pull output stages switch at half the

oscillator frequency. Dead-time is independently pro-

grammedwithanexternalresistor. AUVLOprograminput

providesprecisesystemturn-onandturnoffvoltages.The

LTC3721-1 features peak current mode control with pro-

grammable slope compensation and leading edge

blanking.

■

Low Start-Up and Quiescent Currents

■

Current Mode Operation

■

Single Resistor Slope Compensation

■

V_CCUVLO and 25mA Shunt Regulator

■

Programmable Fixed Frequency Operation to 1MHz

■

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

Hiccup Mode Short-Circuit Protection

5V, 15mA Low Dropout Regulator

■

The LTC3721-1 features extremely low operating and

start-up currents and reliable short-circuit and

overtemperature protection. The LTC3721-1 is offered in

16-pin SSOP and (4mm × 4mm) QFN packages.
