The device High-performance copper-clip package incorporates a driver IC, two power MOSFETs, and Tri-state 3.3V PWM input driver a bootstrap Schottky diode in a thermally enhanced, Skip Mode (low-side gate turn off) input (SMOD ) ultra-compact 6mmx6mm PQFN40 package. Warning flag for over-temperature conditions With an integrated approach, the ZSPM9000s com- Driver output disable function (DISB pin) plete switching power stage is optimized for driver and MOSFET dynamic performance, system induc- Internal pull-up and pull-down for SMOD and tance, and power MOSFET R . It uses innova- DISB inputs, respectively DS(ON) tive high-performance MOSFET technology, which Integrated Schottky diode technology in the dramatically reduces switch ringing, eliminating the low-side MOSFET snubber circuit in most buck converter applications. Integrated bootstrap Schottky diode An innovative driver IC with reduced dead times and Adaptive gate drive timing for shoot-through propagation delays further enhances performance. protection An internal 12V to 5V linear regulator enables the Under-voltage lockout (UVLO) ZSPM9000 to operate from a single 12V supply. A Optimized for switching frequencies up to 1MHz thermal warning function (THWN) warns of potential over-temperature situations. The ZSPM9000 also incorporates features such as Skip Mode (SMOD) Available Support for improved light-load efficiency and a tri-state 3.3V ZSPM8000-KIT: Closed Loop Evaluation Kit pulse-width modulation (PWM) input for compatibility combined for the ZSPM9000 and ZSPM1000 with a wide range of PWM controllers. The ZSPM9000 DrMOS is ideally compatible with Physical Characteristics IDTs ZSPM1000, a leading-edge configurable digital power-management system controller for non- Operation temperature: -40C to +125C isolated point-of-load (POL) supplies.
