DESCRIPTION  
The SP6639/40/53 step-down switching regulators provide high efficiency over a wide range  
of input voltage, output voltage and output current. Duty cycle modulation is used to achieve  
efficiencies over 90% for input voltages from 3.2V to 11.5V. It features a no load quiescent  
current of only 10µA. The circuit contains an internal power MOSFET reducing the external  
component count to only one inductor, a schottky diode and the usual input and output  
capacitors. Theinternaloscillatorisshutdownwhenthecircuitisinregulationtoreducepower  
consumption. Internal inductor damping significantly reduces EMI. This product is offered in  
an 8 lead nSOIC package.
