Microchip Technology EV23R43A Evaluation Board
Microchip Technology EV23R43A Evaluation Board is fully assembled and designed to evaluate and demonstrate the MIC2129 capabilities. These MIC2129 are step-down synchronous DC-to-DC controllers with adaptive on-time control architecture. The MIC2129 is available in 24-pin 4mm x 4mm VQFN and 24-pin 7.8mm x 6.4mm TSSOP package. This evaluation board features an internal bootstrap diode, internal bootstrap LDO, and selectable light load operating mode. The EV23R43A evaluation board operates at a 4.5V to 100V wide input range, 100kHz to 800kHz adjustable switching frequency, and a -40°C to 125°C junction temperature range. This evaluation board is used in communications, automotive, and industrial applications.
