NXP PIP213-12M DC-to-DC converter power train
The PIP213-12M is a fully optimized power train for high-current high-frequency
synchronous buck DC-to-DC converter applications. The PIP213-12M replaces two power MOSFETs, a Schottky diode and a driver IC, resulting in a significant increase in power density. The integrated solution allows for optimization of individual components and greatly reduces the parasitics associated with conventional discrete solutions, resulting in higher system efficiencies at higher operating frequencies.

主要特性：
Input voltage range from 3.3 V to 16 V
Output voltages from 0.8 V to 6 V
Capable of up to 25 A maximum output current at 1 MHz
Operating frequency up to 1 MHz
Peak system efficiency > 85 % at 1 MHz
Automatic Dead-time Reduction (ADR) for maximum efficiency
Internal thermal shutdown
Auxiliary 5 V output
Power ready output flag
Power sequencing functions
Internal 6.5 V regulator for efficient gate drive
Compatible with single and multi-phase Pulse Width Modulation (PWM) controllers
Low-profile, surface-mounted package (8 mm 8 mm 0.85 mm)

应用：
High-current DC-to-DC point-of-load converters
Small form-factor voltage regulator modules
Microprocessor and memory voltage regulators
Intel DriverMOS (DrMOS) compatible
