1 / 42 page  Cool-Power® Rev 2.0 vicorpower.com Page 1 of 42 02/2016 800 927.9474 8 V to 36 Vin Cool-Power ZVS Buck Regulator Family Cool-Power® PI33xx-x0 Product Description The PI33xx-x0 is a family of high efficiency, 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 PI33xx-x0 series, increases point of load performance providing best in class power efficiency. The PI33xx-x0 requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode Buck Regulator. 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-x0 series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20 ns minimum on-time, supports large step down conversions up to 36 Vin. *I2C is a trademark of NXP Semiconductors Features & Benefits • High Efficiency ZVS-Buck Topology • Wide input voltage range of 8 V to 36 V • 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: n n VOUT margining n n Fault reporting n n Enable and SYNCI pin polarity n n Phase delay (interleaving multiple regulators) Applications • Rugged, defense applications • High efficiency systems • High voltage battery operation Package Information • 10 mm x 14 mm x 2.6 mm LGA SiP • 10.5 mm x 14.5 mm x 2.6 mm BGA SiP Device Output Voltage IOUT Max Set Range PI3311-x0 1.0 V 1.0 to 1.4 V 10 A PI3318-x0 1.8 V 1.4 to 2.0 V 10 A PI3312-x0 2.5 V 2.0 to 3.1 V 10 A PI3301-x0 3.3 V 2.3 to 4.1 V 10 A PI3302-x0 5.0 V 3.3 to 6.5 V 10 A PI3303-x0 12 V 6.5 to 13.0 V 8 A PI3305-x0 15 V 10.0 to 16.0 V 8 A |
