ZSPM9010
Ultra-Compact, High-Performance, High-Frequency DrMOS
Brief Description
The ZSPM9010 DrMOS is a fully optimized, ultra-
compact, integrated MOSFET plus driver power
stage solution for high-current, high-frequency, syn-
chronous buck DC-DC applications. The ZSPM9010
incorporates a driver IC, two power MOSFETs, and
a bootstrap Schottky diode in a thermally enhanced,
ultra-compact PQFN40 package (6mmx6mm).
With an integrated approach, the ZSPM9010’s com-
plete switching power stage is optimized for driver
and MOSFET dynamic performance, system induc-
tance, and power MOSFET R_DS(ON). It uses innova-
tive 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. A
thermal warning function (THWN) warns of potential
over-temperature situations. The ZSPM9010 also
incorporates features such as Skip Mode (SMOD)
for improved light-load efficiency with a tri-state 3.3V
pulse-width modulation (PWM) input for compatibility
with a wide range of PWM controllers.
The ZSPM9010 DrMOS is compatible with ZMDI’s
ZSPM1000, a leading-edge configurable digital
power-management system controller for non-
isolated point-of-load (POL) supplies.
