Description

POWER

The RD9 is a special printed circuit board (Figure 1) designed

for rapid prototyping of TinySwitch-based flyback power

supplies in the 1-3 W range. Component positions and an

optimized layout are provided for a complete single output

power supply as shown in Figure 2. Component size and

placement are identical to evaluation board RD8. The board is

designed to accommodate a transformer using an EE16 core

with a 10 pin bobbin (Ying Chin YC-1607 or equivalent^*). In

addition to the power supply circuitry, the RD9 also provides a

prototypingarea onthe secondaryside of the boardfor circuitry

such as additional outputs or voltage and current regulators.

Some typical application circuits that can be constructed using

the RD9 printed circuit board can be found in the TinySwitch

and RD8 data sheets, and Design Ideas DI-4 through DI-8.

board and the RD9 prototyping board are perforated between

the primary and secondary circuit areas, so that the primary half

of the RD8 can be separated and combined with the secondary

half of the RD9.
