LTC1871 DC-DC step-up boost 4-35V converter (HCMODU0111)

A compact but high powered DC-DC step-up (boost) power supply converter module. It features a wide operating supply range with a power supply input voltage between 3.5 to 35V and will step-up this input voltage from 4V to 35V. The module also includes an integrated voltage meter that can measure both the input and output voltages. A voltage selection button allows for easy switching between the two. Together with its high multi-turn precision potentiometer this means any desired output voltage within its supply range can be sent without the need of an external test meter. Additionally LED indicators show power and input or output metering.

Specification:

Item code: HCMODU0111
Input Voltage: 4.5-35V
Output Voltage: Continuous Adjustable (4-35V)
Maximum Output Current: 3A*
Voltmeter Resolution: ±0.1V
Voltmeter Digital Display Range: 4v-45v
Voltmeter Input Voltage Range: Dc 4v-40v

Notes:

Maximum current is dependent on input and output voltages, ambient temperature and cooling. Maximum LTC1871 operating temperature must not exceed 125oC otherwise permanent thermal damage can occur.

Do not set output voltage beyond the modules maximum operating voltage of 35V.

The unit I received only has one PB to the right of the voltage display. How do I turn it On/Off?

Just to be sure I've just checked our stock and they do all have two buttons on them. I can see you did purchase one from us so the only things I can think of is either it's not the correct item or the button is missing? Does it look the same as the module in the image above? Also if you still have the anti-static bag it came in could you possibly check the following things:

1) That the SKU on the label says HCMODU0111

2) Towards the top right of the label there will be a batch date - could you let me know what it is?

Thanks

Thanks for the image. It looks like you have the wrong version of the module. I can see the label is correct but the module in your image is the step down version no the step up. Sorry about this, it must have somehow got mixed up and labelled incorrectly. Could you email sales [at] hobbycomponents.com and just reference this post and we can sort it out from there.
