Dual FET Driver Operates With PWM Control

Designed to operate with a single output high frequency PWM controller in switching power supplies, motor controls and class D amplifiers, SC1405 single-input, dual-output synchronous MOSFET driver operates at frequencies up to 1 MHz with switching times of less than 20 ns. The device has shoot-through protection via a combination of adaptive or programmable methods. And it can be simply interfaced to a low-cost, low-current, single-output PWM controller to create a high-speed, high-current synchronous power supply. The device can operate in a power saving mode by turning off the bottom MOSFET and operating in non-synchronous mode.
