Description
The HNT Series are industry standard, half-brick dc-dc converters that reduce time to market and require less
board space by providing programmable outputs from one, easy-to-use package. These converters offer low
profile, triple output with extremely flexible trim ranges, and current distribution between outputs. This product
range provides onboard conversion of standard telecom, datacom, and industrial input voltages to isolated low
output voltages without the need for any additional cooling.

If output is trimmed up, max current is reduced linearly to 8A at max voltage. Below 10% load, timing, sequencing and ripple may deviate
Measured with a minimum 1µF ceramic cap across output pins, to reduce ripple to typically <30mV a 22µF/6V ceramic cap is recommended
3
Current limit is primary side controlled, the current limit threshold is for total unit power greater than 100W
4
Optimum trim range is 2.4V to 5.15V (refer to trim range table), outside this range turn-on/off overshoot & dynamic response disimprove
5
Optimum trim range from 1.4V to 3.4V (refer to trim range table)
