RDC1-0028, Dual DC-DC Converter on MC34063. Input 5-40V, output 5V and 3.3V. 1.5A

DC-DC converter RDC1-0028 is assembled on the most popular specialized chip MC34063. The module consists of two boards connected by jumpers that can be easily broken to separate the boards into two converters. The size of one board is 25.4 x 25.4 mm. Mounting hole diameter - 3.2 mm.

On each of the boards, DC-DC converters are assembled according to identical schemes, but with different settings.

Scheme

One of them, at input voltages from 5V to 40V, allows you to get stabilized 3.3V at the output with a current of 1A (1.5A maximum), and the other at input voltages from 6V to 40V, gives stabilized 5V at the output with a current of 1A (1 ,5A maximum).
