Product Overview
DC1977A-B is a demonstration board showcases the LTC4121 40V, 400mA synchronous buck battery charger integrated circuit. The DC1977A supports the maximum-power-point tracking (MPPT) feature of the LTC4121EUD to optimize power delivery from photovoltaic cells or highly resistive sources. The LTC4121 feature constant-current-constant-voltage charging capability suitable for lithium ion or lead-acid cells. The LTC4121 may be programmed to charge battery voltages up to 18V with a resistive divider.
- DC1977A Input Voltage range from 4.4 to 40V at I(IN) < 800mA, TA = 25°C
- Adjustable VBAT
