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. 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 pensation and leading edge blanking, while the LTC3723-2 employs voltage mode control with voltage feedforward...
