com RoHS Compliant • • Remote Sense Allows Burst Mode Operation at Low Load Currents Non-Isolated High Efficiency Fixed Frequency (530 kHz) Low Profile Package (8.
5 mm) • Description The SRDB-04C500 is part of the low cost non-isolated dc/dc series.
The module uses a DIP package for ease of layout and space savings, with a low profile of 8.
5mm.
The output is closely regulated and the efficiency is typically 92% at full load.
The unit is designed to be highly efficient and cost-effective.
Features include remote sense, output voltage adjustment and burst mode at light load.
