RVP003系列

The RVP003 is a transformer driver optimized for compact, low-power isolated power supplies with minimal standby power consumption. It requires only basic external components input/output filter capacitors, an isolation transformer, and rectifier circuits to build an isolated power supply with an input voltage range of 6 to 30V, multiple output voltage options, and output power up to 2W. RVP003 integrates two N-channel and two P-channel MOSFETs configured in a full bridge topology. An internal oscillator generates a pair of high-precision complementary signals, ensuring symmetrical switching to prevent magnetic core bias during operation.The device also features frequency synchronization and multiple protection mechanisms. The RVP003 integrates frequency synchronization capability along with multiple protection features. When an external clock signal is applied to the CLK input, the device outputs two complementary drive signals at half the frequency of the input clock. An internal high-precision dead time control circuit ensures reliable operation by preventing simultaneous conduction of the full-bridge power switches under all operating conditions. Additionally, the RVP003 includes built-in overcurrent protection and overtemperature protection, safeguarding the device from damage in abnormal conditions such as output short circuits in the switching power supply.
