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.
Operating from a 4.
5V to 7.
5V input, the ZL1505 combines a 5A, 0.
5W low-side driver and a 3A, 0.
8W high-side driver to support high step-down buck applications.
A unique adjustable gate drive current scheme allows the user to adjust the drive current on both drivers to optimize performance for a wide rage of input/output voltages, load currents, power MOSFETs and switching frequencies up to 1.
4MHz.
An integrated 30V bootstrap Schottky diode is used to charge the external bootstrap capacitor.
