The MCP14628 is a synchronous MOSFET driver used for driving MOSFETs in a rectified bridge arrangement. This type of arrangement is typical of synchronous buck converter topologies.There are two separate drivers contained in the MCP14628. the low-side driver output drives a non-floating or ground reference N-Channel MOSFET. The high-side driver is designed to drive a floating N-Channel MOSFET. since the N-Channel is floating, this output needs to be able to handle the high voltages required to fully turn on the high-side MOSFET. An external bootstrap capacitor is used to provide the additional voltage. The MCP14628 is available in a surface mount 8 Lead SOIC package with a body width of 150 mils and the 8 Lead 3mmX3mm DFN package.
The Microchip Qi wireless LED lantern is a lighting solution with wireless charging capabilities. It is able to draw up to 5W from a base station and charge a Li-Ion battery at 1A.
Battery charging is achieved using a bi-directional synchronous buck converter. The same converter can boost the battery voltage to drive a dimmable string of 3 LEDs at 200mA. A single 8 bit microcontroller...
The advanced Microchip wireless receiver is compatible with Qi 1.2 base stations and is able to draw up to 15W of power that can be used to run portable devices or charge batteries. It allows users to quickly incorporate this receiver into their designs without dealing with the Qi protocol state machine and communication.
This implementation consists of a wireless receiver and a
This is a blank PCB that allows the operation of Microchip Technology’s 8-pin devices to be easily evaluated. Each device pin is connected to a pull-up resistor, a pull-down resistor, an in-line resistor, and a loading capacitor. The PCB pads allow through hole or surface mount connectors to be installed to ease connection to the board. Additional passive component footprints are on the...
