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. Synchronous rectifier timing is adjustable to optimize efficiency. A UVLO program input provides precise system turn-on and turn off voltages. The LTC3723-1 features peak current mode control with programmable slope compensation and leading edge blanking, while the LTC3723-2 employs voltage mode control with voltage feedforward capability.The LTC3723-1/LTC3723-2 feature extremely low operating 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.
