Circuit Ensures Smooth "Soft Start" for Isolated Converter, Limits In-Rush Current
04.04.2018 · Articles
Most dc-dc converters require a soft-start circuit to limit the in-rush current at startup. Although a smooth soft start is required for systems with power-on reset, this is difficult to implement in an isolated converter with a controller on the primary side and a limited duty cycle or current...

The Charge-Pump Option to LDO and Inductor-Based Regulators
03.30.2018 · Articles
Charge pumps are ideal for designs using a larger, main single-voltage power supply that requires lower-current auxiliary voltage sources, and can handle ICs and components that demand multiple voltages. A charge pump is a type of switch-mode power-supply circuit that’s used as a dc-dc converter or regulator with appropriate feedback control...
