ZSPM9000
Ultra-Compact, High-Performance DrMOS Device
Brief Description
Features
The ZSPM9000 DrMOS is a fully optimized, ultracompact, integrated MOSFET plus driver powerstage solution for high-current, high-frequency,
synchronous buck DC-DC applications. The device
incorporates a driver IC, two power MOSFETs, and
a bootstrap Schottky diode in a thermally enhanced,
ultra-compact 6mmx6mm PQFN40 package.

With an integrated approach, the ZSPM9000’s complete switching power stage is optimized for driver
and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). It uses innovative high-performance MOSFET technology, which
dramatically reduces switch ringing, eliminating the
snubber circuit in most buck converter applications.

An innovative driver IC with reduced dead times and
propagation delays further enhances performance.
An internal 12V to 5V linear regulator enables the
ZSPM9000 to operate from a single 12V supply. A
thermal warning function (THWN) warns of potential
over-temperature situations. The ZSPM9000 also
incorporates features such as Skip Mode (SMOD)
for improved light-load efficiency and a tri-state 3.3V
pulse-width modulation (PWM) input for compatibility
with a wide range of PWM controllers.

The ZSPM9000 DrMOS is ideally compatible with
ZMDI’s ZSPM1000, a leading-edge configurable digital power-management system controller for nonisolated point-of-load (POL) supplies.
