STEVAL-ISA036V1
Description
This demonstration board implements a universal
input power supply design for metering and motor
drives applications. It has three outputs: two 15 V
outputs, one of which is isolated and the other has
a primary side ground. There is also a third 5 V
output, which is often used to supply the
microcontroller.
The design is based on the L6565 PWM driver
and the STC04IE170HP, as the main switch.
The design method, however, can also be applied
to an SMPS for other applications working on a
tri-phase mains, and can easily be upgraded for
higher output power.
To achieve very high efficiency, despite the wide
input voltage range, an active start-up network
has been mounted on the board.
For more information regarding the design of an
auxiliary power supply using ESBT^® in flyback
quasi-resonant (QR) topology with the L6565,
refer to application notes AN2254 and AN2528.
For base driving network design, refer to AN2454.
