ZSPM9000 - Renesas

ZSPM9000 High-Performance DrMOS

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 Z.

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 IDT’s ZSPM1000, a leading-edge configurable digital power-management system controller for nonisolated point-of-load (POL) supplies. Benefits
• Fully optimized system efficiency: >93% peak
• Clean switching waveforms with minimal ringing
• 72% space-saving compared to conventional discrete solutions
• Ideally compatible with IDT’s ZSPM1000 true digital PWM controller Features
• .
