UD38251 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD UD38251 38V SYNCHRONOUS BUCK CONVERTER CMOS IC - DESCRIPTION The UTC UD38251 is a monolithic synchronous buck regulator. The device integrates two internal power MOSFETs, and provides 2.5A of continuous load current over a wide input voltage of 8V to 38V. Current mode control provides fast transient response and cycle-by-cycle current limit. An internal soft-start prevents inrush current at turn-on, provides a very pact solution with minimal external ponents. - Features 　- Wide 8V to 38V Operating Input Range - Integrated 140mΩ Power MOSFET Switches - Output Adjustable from VFB(1.00V±2%) to 20V - Up to 93% Efficiency - Internal Soft-Start - Stable with Low ESR Ceramic Output Capacitors - Fixed 160KHz Frequency - Cycle-by-Cycle Over Current Protection - Input Under/Over Voltage Lockout - ORDERING INFORMATION Ordering Number UD38251G-SH2-R Package HSOP-8 HSOP-8 Packing Tape Reel UD38251G-SH2-R - MARKING (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) SH2: HSOP-8 (3) G: Halogen Free and Lead Free .unisonic..tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 7 QW-R115-007.B - PIN CONFIGURATION BS 1 IN 2 SW 3 GND...
