1 / 16 page © Semiconductor Components Industries, LLC, 2010 January, 2010 − Rev. 0 1 Publication Order Number: NCP5252/D NCP5252 2.0 A, 1.0 MHz Integrated Synchronous Buck Regulator with Light Load Efficiency NCP5252 is a synchronous buck regulator with integrated high-side and low-side MOSFETs. The device is capable of operating from a 5 V or 12 V supply and can output a voltage down to 0.6 V. The switching frequency is adjustable from 333 kHz up to 1.0 MHz and has the ability to provide skip mode for light load efficiency. NCP5252 protection features include Under Voltage Lock Out (UVLO), Over Voltage Protection (OVP), Cycle-by-Cycle Current Protection (OCP) and Thermal Shutdown. The parts are packaged in a 3x3mm QFN-16. Features • 1% Accuracy 0.6 V Reference • VCC Voltage 4.5 V to 13.2 V • Adjustable Output Voltage Range: 0.6 V to 5.0 V Vout • Transient Response Enhancement (TRE) Feature. • Lossless Low Side Sense Current Control • Input Voltage Feed Forward Control • Internal Digital Soft−Start • Integrated Output Discharge (Soft−Stop) • Cycle−by−Cycle Current Limit • PGOOD Indication • Overvoltage and Undervoltage Protection • Thermal Shutdown Protection • Power Saving Mode at Light Load • Integrated Boost Diode • QFN−16 (3 mm x 3 mm) • These Devices are Pb−Free and are RoHS Compliant Typical Applications • Desktop Application • System Power • XDSL, Modems, DC−DC Modules • Set Top Box • HD Driver • LED Driver, DVD Recorders Device Package Shipping† ORDERING INFORMATION NCP5252MNTXG QFN16 (Pb−Free) 3000 / Tape & Reel QFN16 CASE 485G MARKING DIAGRAM http://onsemi.com 1 16 N5252 ALYWG G 1 A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. 16 15 14 13 12 11 10 9 1 2 3 4 56 78 VCC BST PGOOD EN/SKIP PGND PGND V5 FREQ_SET QFN16 (Top View) (Note: Microdot may be in either location) NCP5252 |
