STEVAL-ISA029V1 Compact power supply for DVD/set top box evaluation board with three Vout (-30 V, +3.3 V, +12 V)
The STEVAL-ISA029V1 demonstration board is an isolated triple-output flyback converter, suitable for wide-range input voltage operation. The converter is based on the smart power VIPer53-E which, in a single package, integrates an enhanced current-mode PWM controller and a high-voltage MDmesh™ power MOSFET. The switching frequency is set to 60 kHz by means of an external RC network connected to a dedicated pin on the IC. The closed loop regulation is performed on the 12 V output using an optocoupler, which drives the COMP pin of the VIPer53-E. The 3.3 V output is post-regulated using a non-integrated low drop linear voltage regulator to achieve the required accuracy. The negative 24 V output is achieved by means of a discrete linear voltage regulator, made up of a Zener diode, a resistor and a PNP transistor.
