STH05 Series

0.5 Amp STH05 series surface mount SMD10 wide input 48VDC nominal switching regulators

The STH05 series wide input voltage switching regulators, are ideally suited to 48VDC bus POL applications. With efficiency up to 92%, very little energy is wasted as heat so there is no requirement for a heatsink, giving significant space saving and providing flexibility for the PCB design.

These non-isolated DC-DC converters offer a simple step-down voltage conversion and good line/load regulation, low ripple & noise with a low quiescent current (no load) of 3mA. Remote on/off is provided by a control pin, when inhibited the input current is just 1mA. The output has continuous short circuit protection with automatic reset.

The STH05 provide a low-cost point of load (POL) solution for: Distributed DC supply systems not needing isolation but where regulation is required; Embedded computing; Sensors; Robotics; Telecommunications; Instrumentation; Portable & battery-operated equipment
