Beschreibung
Microchip's MCP19215 Digitally Enhanced Power Analog (DEPA) controller [1] can perform all these tasks asa single-chip solution and is ideal for robust applications with added intelligence from the microcontrollercore.The chip is dual-channel, meaning in this particularapplication, it can charge the battery while the LEDlamp is on. Essentially, the application controls twoSEPIC converters that function independently, onecharges the battery while the other one drives a stringof LEDs. Each channel can control both voltage andcurrent. For the LED string, both the current and maximum voltage are controlled on the output side of theconverter. For the battery charging part, things aremore complicated because MPPT mechanisms mustbe incorporated
Eigenschaften
Dual channel, for operating two power outputs from one controllerConstant-current or constant-voltage operation, with dynamic switching between those two control modes, and dynamic adjustment of the output levelCapable of bi-directional power supply controlWide input operating voltage range: 4.5-42VAnalog peak-current mode Pulse-Width Modulation (PWM) controlIntegrated 8-Bit PIC® MicrocontrollerComplete configurability: adjustable output voltage, output current, MOSFET deadtime, leading edge blanking time, thermal responses, slope compensation, over-current protection, over and under voltage lockout levelsAvailable fixed frequency operation from 31 kHz to 2 MHzI2C communication interface12 GPIOIntegrated low-side MOSFET driversIntegrated high voltage linear regulator, with external outputIntegrated temperature sense diodeIntegrated 10 bit A/D converterMinimal external components neededCustom algorithm supportTopologies supported: Boost, SEPIC, Flyback, and Cuk
