DC DC Converters

DC–DC converters are power sources that reside between the input power and the output power. Their purpose is to modify an input voltage and supply an output voltage that is either different from or the same as the input voltage. Their primary function is to convert a DC input voltage to a different voltage, either higher or lower.

PDS1-S5-S12-D Application Field and Working Principle

The PDS1-S5-S12-D is a low-power mixed-signal in-house DC-DC converter used for consumer and commercial applications such as low-cost MLCCs, LCD TVs, mobile phones, LED lighting, and PCs. It offers a wide 4.2V to 36V input voltage range and can provide 48W of output power with an efficiency up to 96%. It is a synchronous rectification DC-DC converter with a constant on-time control. This device uses an integrated power MOSFET and a control circuit that implements a propagation delay compensation function to reduce switching noise and improve efficiency. In terms of protection features, the PDS1-S5-S12-D includes undervoltage lockouts, short-circuit protection, and overcurrent protection.
