1 / 12 page  1 Date: 08/17/04 SP7655 Wide Input Voltage Range 8A, 300kHz, Buck Regulator © Copyright 2004 Sipex Corporation SP7655 FEATURES ■ 2.5V to 28V Step Down Achieved Using Dual Input ■ Output Voltage down to 0.8V ■ 8A Output Capability ■ Built in Low RDSON Power Switches (15 mΩ typ) ■ Highly Integrated Design, Minimal Components ■ 300 kHz Fixed Frequency Operation ■ UVLO Detects Both VCC and VIN ■ Over Temperature Protection ■ Short Circuit Protection with Auto-Restart ■ Wide BW Amp Allows Type II or III Compensation ■ Programmable Soft Start ■ Fast Transient Response ■ High Efficiency: Greater than 95% Possible ■ Asynchronous Start-Up into a Pre-Charged Output ■ Small 7mm x 4mm DFN Package Wide Input Voltage Range 8A, 300kHz, Buck Regulator The SP7655 is a synchronous step-down switching regulator optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12V or 24V distributed power systems step down with 5V used to power the controller. This lower VCC voltage minimizes power dissipation in the part and is used to drive the top switch. The SP7655 is designed to provide a fully integrated buck regulator solution using a fixed 300kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output short circuit protection. The SP7655 is available in the space saving DFN package . ® Advanced TYPICAL APPLICATION CIRCUIT Now Available in Lead Free Packaging DESCRIPTION 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 TOP VIEW Heatsink Pad 1 Connect to Lx Heatsink pad 2 Connect to GND Heatsink pad 3 Connect to V IN PGND PGND GND VFB COMP UVIN GND SS VIN LX LX LX LX VCC GND GND GND BST NC LX LX LX DFN PACKAGE 7mm x 4mm SP7655 PGND VIN VIN VIN 16V 16V CBST 68,00pF L1 2.2uH, Irate=8A C1 22uF CVCC 2.2uF U1 SP7655 PGND 1 PGND 2 PGND 3 GND 4 VFB 5 COMP 6 UVIN 7 GND 8 SS 9 VIN 10 VIN 11 VIN 12 VIN 13 LX 14 LX 15 LX 16 NC 17 BST 18 GND 19 GND 20 GND 21 VCC 22 LX 23 LX 24 LX 25 LX 26 DBST CSS 47nF CP1 22pF 3.30V 0-6A RSET 21.5k,1% GND C3 47uF C4 22uF Notes: 12V VIN SD101AWS 1.
