Using the TPS40170 PWM Buck Controller, this power management reference design provides a regulated 5V to power 2 USB ports at 2.1A each (total 4.2A) in a small form-factor. The design has been optimized for a nominal 12V input and accepts 8-60V with TPS40170.
These development boards are in a half-bridge topology with onboard gate drives, featuring the EPC2030/31/32 eGaN® field effect transistors (FETs).
The EPC9053 is a high efficiency; differential mode Class-E amplifier development board that can operate up to 15 MHz. Higher frequencies may be possible but is currently under evaluation. The purpose of this development board is to simplify the evaluation process of class-E amplifier technology using eGaN FETs.
The EPC9065 is a high efficiency, Zero Voltage Switching (ZVS) differential mode Class-D amplifier development board that operates at, but is not limited to, 6.78 MHz
The MCP73871 Demo Board with Voltage Proportional Current Control is designed to demonstrate Microchip's stand-alone linear Li-Ion battery charger with system power path and load sharing management control solution. The MCP73871 integrates the required elements to meet design challenges when developing new Li-Ion / Li-Polymer batteries powered products.
The MCP73113 is a highly integrated Li-Ion battery charge management controller for use in space-limited and cost-sensitive applications. The MCP73113 provides specific charge algorithms for Li-Ion / Li-Polymer batteries to achieve optimal capacity and safety in the shortest charging time possible. Along with its small physical size, the low number of external components makes the MCP73113 ideall…
DC1583A-A is a 1A high efficiency 2- Cell supercapacitor charger with automatic cell balancing featuring the LTC3625. The LTC3625 is a programmable supercapacitor chargers designed to charge two supercapacitors in series to a fixed voltage of 5.3V or 4.8V from a 2.7V to 5.5V input supply. Automatic cell balancing is achieved during the charging phase, preventing overvoltage damage to either supercapacitor while maximizing charge rate.
The NCP1083QBCGEVB implements a PoE module that converts the power from the Ethernet cable to a lower voltage. The board also supports getting its power from and auxiliary input, in case PoE network is not available. Close to the switching MOSFET voltages on the board may exceed 200 V (@250 kHz). Temperature of board and its components may exceed 85°C during normal operation.
The NCP1654GEVB is a Power Factor Controller to efficiently drive Continuous Conduction Mode (CCM) step-up pre-converters. The NCP1654 allows operation in Follower Boost mode to drastically lower the pre-converter size and cost, in a straight-forward manner. The NCP1654 is a continuous conduction mode and fixed frequency controller (65kHz). The coil (650 uH) is selected to limit the peak to peak …
