High Efficiency Buck-Boost Battery Charger

Sep 18 2017

Today’s battery chargers are expected to support a variety of battery chemistries and accept a range of input voltages. In many applications, the input voltage range can vary from below the output battery voltage to above the battery voltage, requiring both step-down and step-up capability. In this video, we will show how the LTC4020 controller meets these challenges, how it works and its main features. The LTC4020 buck-boost battery charger works over a wide 4.5V to 55V input range, and produces output voltages up to 55V. It includes a buck-boost DC/DC controller and a PowerPath™ battery charger, optimized for a variety of battery chemistries. The LTC4020 has many features, including PowerPath instant-on, timer-based charging, battery temperature monitoring, input voltage regulation, charging status and fault reporting.
