RVPW015 Series Coming Soon

RVPW015 is a highly integrated power control IC designed to support multiple power supply topologies, including Flyback, Boost, and Buck converters. It is compatible with various output voltage feedback methods such as Secondary-Side Regulation (SSR), Primary-Side Regulation (PSR), and resistive voltage divider feedback. PSR operation is supported at switching frequencies up to several hundred kHz. The internal output voltage sampling circuit is capable of operating in both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM), with a sampling time window requirement as short as 400ns. An integrated loop compensation circuit with fast dynamic response ensures excellent loop stability and rapid transient performance for the switching power supply. RVPW015 incorporates multiple control and protection functions, while requiring only minimal external components. It offers flexible design capabilities through configurable external resistors. A single resistor can be used to implement startup, feedforward compensation, and programmable turn-off speed control of the internal power MOSFET. Another resistor allows for programming the peak current of the power MOSFET, enabling a “lossless” current sensing method. With just two resistors, both input undervoltage protection (UVP) and input overvoltage protection (OVP) thresholds can be independently defined. The RVPW015 also integrates comprehensive protection features, including overload protection (OLP), output short-circuit protection (SCP), output overvoltage protection (OVP), and over-temperature protection (OTP). Once a fault condition is cleared, the chip automatically recovers, enhancing system robustness and maximizing the reliability of the power supply.
