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  图1。PIP213-12M方框图 典型应用  图2。PIP213-12M 在四相转换器的典型应用（采用四个PIP213-12M 器件可使连续输出电流100 A，工作频率500 kHz） |
