1 / 37 page  Cool-Power® Rev 1.3 vicorpower.com Page 1 of 37 02/2016 800 927.9474 36 Vin to 60 Vin Cool-Power ZVS Buck Regulator & LED Driver Cool-Power® PI354x-00 Product Description The PI354x-00 is a family of high input voltage, wide input range DC-DC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-in-Package (SiP). The integration of a high- performance Zero-Voltage Switching (ZVS) topology, within the PI354x-00 series, increases point of load performance providing best in class power efficiency. The PI354x-00 requires only an external inductor, two voltage selection resistors and minimal capacitors to form a complete DC-DC switching mode buck regulator. PI354x-00 Family can operate in constant voltage output for typical buck regulation applications in addition to constant current output for LED lighting and battery charging applications. Features • High Efficiency HV ZVS-Buck Topology • Wide input voltage range of 36 V to 60 V • Very fast transient response • Constant voltage or constant current operation • Constant current error amplifier and reference • Power-up into pre-biased load • Parallel capable with single wire current sharing • Two phase interleaving • Input Over/Undervoltage Lockout (OVLO/UVLO) • Output Overvoltage Protection (OVP) • Overtemperature Protection (OTP) • Fast and slow current limits • Differential amplifier for output remote sensing • User adjustable soft-start & tracking • -40°C to 125°C operating range (TJ) Applications • HV to PoL Buck Regulator Applications • Computing, Communications, Industrial, Automotive Equipment • Constant current output operation: • LED Lighting • Battery Charging Package Information • 10 mm x 10 mm x 2.6 mm LGA SiP Device Output Voltage IOUT Max Set Range PI3542-00-LGIZ 2.5 V 2.2 V to 3.0 V 10 A PI3543-00-LGIZ 3.3 V 2.6 V to 3.6 V 10 A PI3545-00-LGIZ 5.0 V 4.0 V to 5.5 V 10 A PI3546-00-LGIZ 12 V 6.5 V to 14 V 9 A |
