SS6578
SS6578 is HIGH EFFICIENCY STEP DOWN DC/DC CONTROLLER manufactured by Silicon.
..
High-Efficiency, Step-Down DC/DC Controller
Features
4V to 18V input voltage operation. High-efficiency (up to 95%). Low quiescent current at 90µA. Pulse-skipping and pulse-frequency modulation. Inputs-unmitted current-sense parator. Duty-cycle adjustable. 90KHz to 280KHz oscillator frequency. Power-saving shutdown mode (8µA typical). Push-pull driver output.
DESCRIPTION
The SS6578 is a high performance step-down DC/DC controller, designed to drive an external P-channel MOSFET to generate programmable output voltages. Two main schemes of Pulse-Skipping and Pulse-Frequency Modulation are employed to maintain low quiescent current and high conversion...
