Shouding SD8906A 600mA, 1.5MHz Synchronous Step-Down Converter The SD8906A is a constant frequency, current mode PWM step-down converter.The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as 0.6V. The SD8906A can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The SD8906A is offered in a low profile (1mm)5-pin, thin SOT package, and is available in an adjustable version and fixed output voltage of 1.2V,1.5V, 1.8V,2.5V and 3.3V. FEATURES  High Efficiency: Up to 96%  Output Voltage as Low as 0.6V  1.5MHz Constant Frequency Operation  100% Duty Cycle in Dropout G  600mA Output Current  Low Quiescent Current: 35µA  No Schottky Diode Required  Slope Compensated Current Mode Control for Excellent Line and Load  2.3V to 5.5V Input Voltage Range N I  Short Circuit Protection Transient Response  1µA Shutdown Current  Thermal Fault Protection  Tiny SOT23-5 Package  Inrush Current Limit and Soft Start D APPLICATIONS U  Digital Still and Video Cameras  Wireless and DSL Modems
