1 / 8 page ACE710C 1A Synchronous PWM Boost converter VER 1.1 1 Description The ACE710C is a step-up converter that provides a boosted output voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 0.9V, and only consumes 15uA at standby, making it an ideal choice for single cell alkaline/NiMH battery operations. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. ACE710C is available in SOT23-5 Package. Features Efficiency up to 95%@Vin=4.0V, Vout=5.0V Typical 15uA standby current 1MHz Switching Frequency allows small inductor and output cap Input boost-strapping allows using small or no input cap Low Vin Start-up Voltage down to 0.9V Ideal for Single Alkaline Cell operations Maximum Output Current up to 1A Low Noise PWM control Internally Compensated Current Mode Control Internal Synchronous Rectifier Logic Control Shutdown (IQ<1uA) Available in SOT23-5 Applications One to Three Cell Battery Operated Devices Medical Instruments Bluetooth Headsets Flash-Based MP3 Players Noise Canceling Headphones |
