ZVS Regulators PI332x-00 14 42V ZVS Buck Regulator IN Product Description Features & Benefits The PI332x-00 is a family of high-input-voltage, wide-input-range HighEfficiency HV ZVS Buck Topology DC-DC ZVS Buck regulators integrating controller, power Wide input voltage range of 14 42V switches and support components all within a high-density System-in-Package (SiP). Powerup into pre biased load The integration of a high-performance Zero-Voltage Switching Parallel capable with singlewire current sharing (ZVS) topology, within the PI332x-00 series, increases point-of-load Input Over/Undervoltage Lockout (OVLO/UVLO) performance providing best-in-class power efficiency. The PI332x-00 requires only an external inductor, two voltage selection Output Overvoltage Protection (OVP) resistors and minimal capacitors to form a complete DC-DC Overtemperature Protection (OTP) switch-mode buck regulator. Fast and slow current limits Output Voltage Differential amplifier for output remote sensing Device I Max OUT Set Range Useradjustable soft start & tracking 3.3V 2.2 4.0V 22A PI3323-00 40 to 120C operating range (T ), LGIZ models INT PI3325-00 5.0V 4.0 6.5V 20A 55 to 120C operating range (T ), LGMZ models INT Applications HV to PoL Buck Regulator Applications Computing, Communications, Industrial, Automotive Equipment Package Information 10 x 14 x 2.56mm LGA SiP Note: Product images may not highlight current product markings.
