General Description
The SS8392 using the external NMOSFET. It
is a high efficiency boost converter with
600mV feedback voltage. A switching
frequency of 550KHz minimizes solution
footprint by allowing the use of tiny low profile
inductors and ceramic capacitors. The
current mode PWM/PFM design is internally
compensated, and the device has a 1.6V
startup voltage with 1mA load. It needs few
external components, only inductance,
resistance and capacitance can meet the
