ACE Technology ACE708
The ACE708 is a step-up converter that provides a boosted output voltage from a low voltage source. The current mode PWM design is internally compensated, reducing external parts count.DESCRIPTION
Because of its proprietary design, it starts up at a very low input voltage down to 850mV, making it an ideal choice for single cell alkaline/NiMH battery operations. A switching frequency of 1.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.FEATURES
● Up to 95% Efficiency● 1.2MHz 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 850mV Ideal for Single Alkaline Cell operations
● Maximum Output Current up to 300mA
● Low Noise PWM control
● Internally Compensated Current Mode Control
● Internal Synchronous Rectifier
● Logic Control Shutdown (IQ<1uA) Application
● One to Three Cell Battery Operated Devices
● Medical Instruments
● Bluetooth Headsets
● Flash-Based MP3 Players
● Noise Canceling Headphones
