Microchip Dual Boost/SEPIC Evaluation Board Boost Controller for MCP19215 for LED Lighting Systems, Battery Charger,

The MCP19215 Dual Channel Controller Evaluation Board demonstrates how the MCP19215 device operates in Boost and SEPIC topologies over a wide input voltage and load range. Nearly all operational and control system parameters are programmable by utilizing the integrated PIC controller.

• Input voltage range: 8V to 15V
• Output voltage: default 20V for both channels (can be software adjusted from input voltage + 1V to 24V for channel 1 and 9V to 24V for channel 2)
• Default output current: 0.2A (can be software adjusted from 0A to 1A)
• 300 kHz switching frequency
• Status report (including errors, input voltage, output voltage and current) via I2C communication
• Under voltage lockout (UVLO) and overvoltage lockout (OVLO) with programmable thresholds (via software)
