PI33/PI34/PI35xx Series Cool-Power® ZVS Switching Regulators: Buck 48, 24 and 12V to PoL Buck Regulator Applications, Computing, Communications, Industrial, Automotive Equipment. Constant current applications: LED Lighting and Battery Charging. Description Features & Benefits PI33/PI34/PI35xx Cool-Power® ZVS Buck Regulators offer board‑level designers maximum power density and flexibility for high-efficiency point-of-load DC-DC regulation. The integration of a high performance Zero-Voltage Switching (ZVS) topology increases point-of-load performance, providing best-in-class power efficiency up to 98%. Cool-Power ZVS Regulators are highly integrated with control circuitry, power semiconductors and support components in a high density LGA System in Package (SiP). • Wide Input Operating Ranges Power delivery can be further increased by inter-leaving multiple buck regulators using single wire current sharing. The ZVS topology enables high-frequency operation maximizing efficiency by minimizing the significant switching losses associated with conventional hard switching buck regulators. The high switching frequency of the Cool-Power ZVS Regulators reduces the size of the external filtering components, improving power density while enabling fast line and load dynamic response. These regulators maintain high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on-time, supports step down conversion for input voltages up to 60V. The Cool-Power ZVS series offers buck regulators for 12VIN, 24VIN and 48VIN nominal systems. All devices within their respective series share the same footprint. ■■12VIN nominal (8 to 18VIN) ■■24VIN nominal (8 to 36VIN) ■■48VIN nominal (30 to 60VIN) ■■–40°C to 125°C temperature operating range • Simple to Use; Fast Development Time ■■Internal compensation - few external components ■■No additional design or additional settings required • High Efficiency ■■>96% peak 48VIN to 12VOUT ■■>96% peak 24VIN to 12VOUT ■■>95% peak 12VIN to 5VOUT ■■Light load and full load high efficiency performance • Flexible and Rich Feature Set ■■Paralleling and single wire current sharing ■■Frequency synchronization ■■User adjustable soft-start & tracking ■■PI33xx optional I2C™ telemetry & functionality nn VOUT margining nn Fault reporting nn Enable and SYNCI pin polarity nn Phase delay (for interleaving multiple regulators) • High Density Packaging Platform ■■10 x 14 x 2.5mm SiP LGA ■■10.5 x 14.5 x 3.05mm BGA ■■10 x 10 x 2.5mm SiP LGA ■■10.5 x 10.5 x 3.05mm BGA Example Power Chain Total Area (With Required Components) 10mm 19mm ZVS Buck BCM ZVS Buck Regulator Inductor ZVS Buck VIN CIN PGND ZVS Buck PI33xx VOUT VS1 VOUT COUT REM 12V 48V L1 VIN SYNCI SYNCO EN TRK ADJ EAO SGND 380VDC Cool-Power ® Array of 2 14mm 5V Cool-PowerCool-Power Required Components and GeneralCool-Power Dimensions ZVS Buck Regulator schematic with minimum with required components and required external components general dimensions vicorpower.com Rev 2.4 09/2018 PI34xx Efficiency (5VOUT) Part Numbers Options: 100 95 x = 0 (Standard) x = 2 (I2C functionality & programmability) Efficiency % 90 85 80 Part Number 75 Output Range Rating Set Range PI3420-00-LGIZ 1.0V 1.0 – 1.4V 15A PI3421-00-LGIZ 1.8V 1.4 – 2.0V 15A PI3422-00-LGIZ 2.5V 2.0 – 3.1V 15A PI3423-00-LGIZ 3.3V 2.3 – 4.1V 15A PI3424-00-LGIZ 5.0V 3.3 – 6.5V 15A 70 12V (8 – 18VIN) 65 60 55 50 0 1 3 2 4 5 6 7 9 8 10 12 11 13 14 15 Load Current (A) 8VIN 18VIN 12VIN 24V (8 – 36VIN) I2C ™ [b] Functionality PI3311-x0-LGIZ 1.0V 1.0 – 1.4V 10A PI3311-x1-LGIZ 1.0V 1.0 –1.4V 15A PI3318-x0-LGIZ 1.8V 1.4 – 2.0V 10A PI3318-x1-LGIZ 1.8V 1.4 – 2.0V 15A PI3312-x0-LGIZ 2.5V 2.0 – 3.1V 10A PI3312-x1-LGIZ 2.5V 2.0 – 3.1V 15A 85 PI3301-x0-LGIZ 3.3V 2.3 – 4.1V 10A 80 PI3301-x1-LGIZ 3.3V 2.3 – 4.1V 15A PI3302-x0-LGIZ 5.0V 3.3 – 6.5V 10A 65 PI3302-00-BGIZ 5.0V 3.3 – 6.5V 10A 60 PI3302-03-LGIZ  [a] PI33xx Efficiency (12VOUT) 100 95 Efficiency 90 75 70 5V 3.3 – 6.5V 15A PI3325-00-LGIZ 5.0V 4.0 – 6.5V 20A PI3303-x0-LGIZ 12V 6.5 – 13.0V 8A PI3305-x0-LGIZ 15V 10.0 – 16.0V 8A 3.3V 2.2 – 4.0V 22A PI3525-00-LGIZ 5.0V 4.0 – 6.5V 20A PI3526-00-LGIZ 12.0V 6.5 – 14V 18A PI3542-00-LGIZ 2.5V 2.2 – 3.0V 10A PI3542-00-BGIZ 2.5V 2.2 – 3.0V 10A 96 PI3543-00-LGIZ 3.3V 2.6 – 3.6V 10A 95 PI3543-00-BGIZ 3.3V 2.6 – 3.6V 10A 94 PI3545-00-LGIZ 5.0V 4.0 – 5.5V 10A 55 50 0 1 2 3 4 5 6 7 8 Load Curent (A) VIN = 17.4V VIN = 24V VIN = 36V 48V (30 – 60VIN) PI3523-00-LGIZ PI35xx Efficiency (12VOUT) 48V (36 – 60VIN) 98 Efficiency (%) 97 93 92 91 90 89 PI3545-00-BGIZ 5.0V 4.0 – 5.5V 10A PI3546-00-LGIZ 12.0V 6.5 – 14.0V 9A PI3546-00-BGIZ 12.0V 6.5 – 14.0V 9A [a] 1.8 3.6 5.4 7.2 9 10.8 12.6 14.4 16.2 18 Input operating range is limited to 11 – 36V is a trademark of NXP Semiconductors [b] I2C Load Current (A) VIN: 48V 30V 60V vicorpower.com Rev 2.4 09/2018 Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Vicor: PI3523-00-LGIZ PI3526-00-LGIZ PI3525-01-LGIZ
