Dual ±15 V regulator for analogue circuits

The KEHIPI 2001708005 is a DC-DC buck-boost module that accepts 4.8–35 V input and produces a positive-negative ±15 V rail at up to 660 mA. It targets designers powering operational amplifiers, sensors or audio front-ends from a single supply.

Input range and protection limits

The converter operates from 4.8 V to 35 V and tolerates brief excursions to 40 V, but the enable pin must not share the VIN potential or the output becomes unstable. Short-circuit protection is self-resetting yet cannot survive prolonged shorting, and a minimum load of 30 mA is required for regulation.

Capacity, headroom and derating

Rated output is 660 mA per rail with typical efficiency of 88 % at 24 V input, while ripple stays at 35 mV / 30 mV under full load. At lower input voltages the usable current drops according to the derating curve, so high-current designs must verify the curve before committing to the 660 mA figure.

Questions about this item

Should I pick the ±15 V 660 mA version or look for a higher-current model?

This module delivers ±15 V at 660 mA per rail with a 30 mA minimum load; choose it when your op-amp or sensor circuit stays within that current envelope.

What does the 88 % efficiency figure mean when the board is powered from a 24 V source?

At 24 V input the converter reaches 88 % conversion efficiency, so roughly 12 % of input power becomes heat while supplying full ±15 V output.

The input range is 4.8–35 V — what happens at the extremes?

Operation is specified from 4.8 V to 35 V DC; below 4.8 V the regulator cannot maintain ±15 V, and above 35 V the input voltage exceeds the rated maximum.
