Digital power Supply based on RL78/I1A microcontrollers implements power factor correction(PFC), advanced safety and communication functions in a single chip, enabling lower cost and regulation compliance.

RL78/I1A adopts the Renesas 16-bit RL78 CPU, which achieves both high computational performance and ultra-low power consumption, and includes 32 to 64 kilobytes of Flash memory in 20- to 38-pin packages. It also embeds hardware safety functions for IEC60730 compliance.

The board can support input of 100Vac – 280Vac and Output of 30V at 1A current. The power factor achieved in the soltuion is greater than 0.95 and total harmonic distortions of less than 10%.

• Single-chip solution for power stage control.
• Variable frequency drive
• Ultra low power consumption, high system efficiency
• Key protection features implemented like Input Voltage (UVLO / OVLO), Output Voltage ( Open load ), Output short circuit
• Supports multiple sensor and user interface controls
• Easy integration into building automation network
• Enables high performance intelligence power supply at low system cost

• Digital Power Supplies
• Battery Chargers etc.
