1 / 10 page ACE7215C 1.5A 1.5MHz Synchronous Buck Converter VER 1.1 1 Description The ACE7215C is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40uA and drops to <1uA in shutdown. The 2.5V to 6V input voltage range makes the ACE7215C ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage. The ACE7215C is available in SOT23-5 and DFN2*2-6L package. Features High Efficiency: Up to 96% 2.5V to 6V Input Voltage Range 1.5MHz Constant Frequency Operation No Schottky Diode Required Low Dropout Operation:100% Duty Cycle PFM Mode for High Efficiency in Light Load Over temperature Protected Low Quiescent Current: 40μA Short Circuit Protection Inrush Current Limit and Soft Start Available in SOT23-5 and DFN2*2-6L Application Cellular and Smart Phones Wireless and DSL Modems PDAs Portable Instruments Digital Still and Video Cameras PC Cards |
