Transformer Driver, RVP010-PPN-R, RECOM

The RVP010 is a push-pull transformer driver specifically designed for small form factor, low standby power isolated micro power supplies. It requires only a simple peripheral configuration, including input and output filter capacitors, an isolation transformer, and a rectifier circuit, to achieve an isolated power supply with a 3.3V or 5V input, an output voltage ranging from 3.3V to 24V, and output power between 1W and 3W. The RVP010 integrates an internal oscillator that generates a pair of high-precision complementary signals to drive two N-channel switches. Its symmetrical internal architecture ensures excellent balance between the two power switches, minimizing magnetic bias during operation. The chip includes an enable pin (EN) and supports two selectable operating frequencies, which can be chosen by either floating or grounding the CLK pin. A high-precision dead-time control circuit is also integrated to prevent simultaneous conduction of the two power switches under all operating conditions.
