Microchip announces the latest controller Digitally Enhanced Power Analogue (Fathom) – i MCP19118 and MCP19119 (MCP19118/9). They offer an analog PWM control simple but effective buck converter DC-DC synchronous up to 40V, the configurability of an MCU digital. They are also the first devices on the market to combine 40V operation and communication interfaces PMBus™. Queste caratteristiche consentono un rapido sviluppo dei circuiti di conversione di potenza con un loop analogico di controllo programmabile nel firmware del core PIC® MCU 8-bit integrato. This integration and flexibility are ideal for applications in power conversion, such as battery charger, LED-driving, USB Power Delivery, point-of-load power supplies and Automotive.
Through the integration of a microcontroller supervision, devices MCP19118 / 9 can create programmable power supplies. The settings key system, come frequenza di commutazione tra 100 kHz to 1.6 MHz, limitations of current and voltage thresholds, can be adjusted on-the-fly during operation through the input of commands written to the registers in the device.
