NON-ISOLATED DC/DC CONVERTERS 4.5V-13.2V Input 1.0V-5.0V/6A Output x7AH-06E Series • Non-Isolated • OCP/SCP (Latch off) • Fixed Frequency (400kHz) • Trim Function • Remote On/Off • Low Profile Package (7.82mm) • Under-voltage Lockout (UVLO) Description The Bel x7AH-06Exx0 is part of the low cost non-isolated dc/dc converter series. The modules use a surface mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82mm. The output is closely regulated and the efficiency of 3.3V output module is typically 91% at full load. Typical features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection. Part Selection Output Voltage 5.0V Input Voltage 8.0 – 13.2V Max. Output Current 6A Max.

Output Trim Equations Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal output voltage of the converter (Vnom) are shown below. The Trim Down resistor should be connected between the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of the resistors should be used for any given application.
