Description

General part information

LTC3721-1 Series

The LTC3721-1 push-pull PWM controller provides all of the control and protection functions necessary for compact and highly efficient, isolated power converters. High integration minimizes external component 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 compensation 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.ApplicationsTelecommunications, Infrastructure Power SystemsDistributed Power ArchitecturesServer Power SuppliesHigh Density Power Modules
