www.DataSheet4U.com Synchronous Step-Down MOSFET Drivers ZL1505 The ZL1505 is an integrated high-speed, high-current N-channel MOSFET driver for synchronous step-down DC-DC conversion applications.

When used with Zilker Labs Digital-DC™ PWM controllers, the ZL1505 enables dynamically adaptive dead-time control that optimizes efficiency under all operating conditions.

A dual input PWM configuration enables this efficiency optimization while minimizing complexity within the driver.
