Mikroe Boost 3 Click
Mikroe Boost 3 Click has a boost converter with an integrated current mirror function. The Mikroe Boost 3 Click board features the Texas Instruments (TI) TPS61391 700kHz Pulse-Width Modulating (PWM) Step-Up Converter with a 70V switch FET and an input voltage of up to 5.5V. The TPS61391 includes an accurate current mirror with two selectable gain options (1:5 or 4:5). The TI converter provides high optical power protection with an additional FET in series with the APD power path, with a typical response time of 0.5µs.
