Synchronous Step-Down MOSFET Drivers

ZL1505

Features

• High-speed, high-current drivers for synchronous

N-channel MOSFETs

• Adaptive dead-time control optimizes efficiency

when used with Digital-DC controllers

• Integrated 30V bootstrap Schottky diode

• Capable of driving 40A per phase

• Supports switching frequency up to 1.4MHz

- >4A source, >5A sink low-side driver

- >3A source/sink high-side driver

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. An internal watchdog circuit

prevents excessive shoot-through currents and protects

the external MOSFET switches.

- <10ns rise/fall times, low propagation delay

combinations

• Internal non-overlap watchdog prevents

shoot-through currents

Applications*(see page 12)

• High efficiency, high-current DC/DC buck converters

with digital control and PMBus™

• Multi-phase digital DC/DC converters with phase

adding/dropping

• Power train modules

• Synchronous rectification for secondary side isolated

power converters

The ZL1505 is specified over a wide -40°C to +125°C

junction temperature range and is available in an

exposed pad DFN-10 package.
