ZVS Regulators PI34xx-00-LGIZ 8 18V , 15A ZVS Buck Regulator IN Product Description Features & Benefits The PI34xx-00 is a family of high-efficiency DC-DC ZVS Buck High-efficiency ZVS Buck topology regulators integrating the controller, power switches and support Input voltage range of 8 18V components within a high-density System-in-Package (SiP). Very fast transient response The PI34xx-00 is designed to achieve optimum efficiency at low input voltage ranges (8 18V). The utilization of zero-current soft Power-up into pre-biased load turn-on provided by the high-performance ZVS topology within the High-accuracy pre-trimmed output voltage PI34xx-00 series increases point-of-load performance, providing best in class power efficiency with high throughput power. User adjustable soft start & tracking The PI34xx-00 requires only an external inductor and minimal Parallel capable with single-wire current sharing capacitors to form a complete DC-DC switching-mode Input over/undervoltage lockout (OVLO/UVLO) buck regulator. Output overvoltage protection (OVP) Output Voltage Device I Max Overtemperature Protection (OTP) OUT Set Range Fast and slow current limits PI3423-00-LGIZ 3.3V 2.3 4.1V 15A 40 to 125C operating range (T ) INT PI3424-00-LGIZ 5.0V 3.3 6.5V 15A Applications The ZVS architecture enables high-frequency operation while minimizing switching losses and maximizing efficiency. The High-Efficiency Systems high-switching-frequency operation reduces the size of the external Computing, Communications, Industrial, filtering components, improves power density, and enables very Automotive Equipment fast dynamic response to line and load transients. The ZVS architecture enables operation up to 750kHz while Package Information minimizing switching losses and the use of variable frequency extends high efficiency over a very wide dynamic range. The 10 x 14 x 2.6mm LGA SiP PI34xx-00 series has a minimum on time of 20ns which enables large step-down conversion ratios. Note: Product images may not highlight current product markings.
