Overview
Cool-Power® ZVS Switching Regulators PI33xx-x1 8V to 36VIN, 15A Cool-Power ZVS Buck Regulator Product Description The PI33xx-x1 is a family of high efficiency, wide input range DCDC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-inPackage (SiP).
The integration of a high performance ZeroVoltage Switching (ZVS) topology, within the PI33xx-x1 series increases point of load performance providing best in class power efficiency.
The PI33xx-x1 requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode Buck Regulator.

1V Table 1 – PI33xx-x1 portfolio IOUT Max 15A 15A 15A 15A The ZVS architecture also enables high frequency operation while minimizing switching losses and maximizing efficiency.
The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients.
The PI33xx-x1 series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on-time, supports large step down conversions up to 36VIN.
Features & Benefits • High Efficiency ZVS-Buck Topology • Wide input voltage range of 8V to 36V • Very-Fast transient response • High accuracy pre-trimmed output voltage • User adjustable soft-start & tracking • Power-up into pre-biased load (select versions) • Parallel capable with single wire current sharing • Input Over / Undervoltage Lockout (OVLO/UVLO) • Output Overvoltage Protection (OVP) • Overtemperature Protection (OTP) • Fast and slow current limits • -40°C to 125°C operating range (TJ) • Optional I2C* functionality & programmability: nnVOUT margining nnFault reporting nnEnable and SYNCI pin po...
