Typical Application:
Aimtec’s half brick models can operate independently. However, to enhance their performance and to ensure precision of
the output signal parameters the following connections are recommended:

Please refer to our Application note: Ripple and Noise Measurement of Brick & POL DC-DC Converters.
ON/OFF Control:
The converter output can be disabled by moving SW to position “a” –
connected to –Vin with voltage level between -0.7 and 0.4V.
When SW is open in position “b”, the converter is ON and operates
normally.
The SW can be replaced by a NPN transistor with connection as follows:
Output Voltage Trim connection:
The output voltage can be adjusted by connecting trim resistors as shown.

The values can be determined according to the following formulas where Δ% is the desirable voltage adjustment in percentage and Vo is
the Nominal value of the Output Voltage:
