Microchip Technology introduced their MCP19111 Digitally Enhanced Power Analog controller. The MCP19111 is a new hybrid, digital and analog power-management device. The controller increases the capabilities of high-efficiency, analog-based power designs. The MCP19111 controller is priced at $2.81 each. It is available in a 5×5 mm, 28-pin QFN package.
Microchip Technology introduced the PIC12F(HV)752 microcontrollers. The new family of 8-bit MCUs feature an integrated Complementary Output Generator (COG) peripheral, 1.75 KB of self read-write program memory, 64B of RAM, an on-chip 10-bit ADC, Capture-Compare PWM modules, high-performance comparators (down to 40ns response), and two 50 mA-capable I/O’s. The PIC12F752 microcontroller is available in 8-pin 3 mm x 3 mm DFN, PDIP and SOIC packages. The MCU is priced at $0.56 each in 10,000-unit quantities. The PIC12FHV752 is available in the same package options for $0.60 each.
Microchip Technology introduced the Quarter Brick DC/DC Converter Reference Design and DC/DC LLC Converter Reference Design. The reference designs feature intelligent control of the power converter and serial system communication, remote control and monitoring, and full fault protection. The reference designs are implemented using Microchip’s dsPIC33F GS digital-power Digital Signal Controllers (DSCs), which provide fully digital control of the power-conversion and system-management functions. The DC/DC Reference Designs (software, Gerber files, MATLAB models, Webinars and application notes) can be downloaded for free.
The Microchip dsPIC33F GS 16-bit dsPIC digital signal controllers (DSC) can be configured for a variety of topologies. The eight new DSCs offer up to 18 channels of Pulse-Width-Modulators (PWMs) with 1 nanosecond resolution, enabling a number of completely independent digital control loops. The dsPIC33F GS DSCs start at $2.93 each in 10,000-unit quantities. The dsPIC33FJ32GS406, dsPIC33FJ64GS406, dsPIC33FJ32GS606 and dsPIC33FJ64GS606 are available in 64-pin TQFP and 9×9 mm QFN packages. The dsPIC33FJ32GS608 and dsPIC33FJ64GS608 are available in an 80-pin TQFP package. The dsPIC33FJ32GS610 and dsPIC33FJ64GS610 are available in a 100-pin TQFP package.
