LTC3721-1 Datasheet | Linear Technology

LTC3721-1 Push-Pull PWM Controller Features - 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 - Low Start-Up and Quiescent Currents - Current Mode Operation - Single Resistor Slope pensation - VCC UVLO and 25m A Shunt Regulator - Programmable Fixed Frequency Operation to 1MHz - Soft-Start, Cycle-by-Cycle Current Limiting and Hiccup Mode Short-Circuit Protection - 5V, 15m A Low Dropout Regulator - 16-Pin SSOP and (4mm × 4mm) QFN Packages U APPLICATIO S - Telemunications, Infrastructure Power Systems - Distributed Power Architectures - Server Power Supplies - High Density Power Modules DESCRIPTIO The LTC®3721-1 push-pull PWM controller provides all of the control and protection functions necessary for pact and highly efficient, isolated power converters. High integration minimizes external ponent count, while preserving design flexibility. The robust push-pull output stages switch at half the oscillator frequency. Dead-time is independently programmed with an external resistor. A UVLO program input provides precise system turn-on and turn off voltages. The LTC3721-1 Features peak current mode control with programmable slope pensation and leading edge blanking. 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. , LTC and LT are registered trademarks of Linear Technology Corporation. TYPICAL APPLICATIO Isolated Push-Pull...
