The LTC4000''s wide input voltage range (3V–60V) and virtually unlimited current capability produces efficient, high performance, full-featured battery chargers that rival the performance of dedicated charger ICs.
With reduced input current, the charger will reduce first the charge current and then the system load current. Resistances between the supply and charger can prevent the charger from pulling the maximum power from its supply without collapsing the supply and hitting the char-ger’s undervoltage lockout.
When the battery voltage reaches 4.1 or 4.2 V (typical), the charger switches to a constant voltage phase to eliminate overcharging. Superior battery test equipment manages the transition from CC to CV smoothly to ensure maximum capacity is reached without risking damage to the battery.
In buck mode, the battery current is 5.479 A if the DAC current reference signal code is 3229(DEC). The battery current is 34.932 A if the DAC current reference signal code is 20522(DEC), and the battery current is 49.942 A if the DAC current reference signal code is 29360(DEC).
This reference design proposes a solution for high-current (up to 50 A) battery tester applications supporting input (bus) voltages from 8 V–16 V and output load (battery) voltages from 0 V–5 V.
Because high temperature effects the drift of some device in the system, the relationship between the current control signal and the real output current is not linear. Three point data is used to calibrate the CC control considering the drift in a high current situation.

In this paper, a model-based control scheme for a DC-DC power converter as a battery charger is presented. The proposed DC-DC converter for this task is a high-gain step-down converter based on the switched inductor concept.
For example, if VBUS is 4.3 V, VBAT is 4.2 V and total resistance from BUS input to battery is 150 mW, the maximum current to the battery is 660 mA. Realistically, no high-side NMOS buck converter can reach 100% duty cycle. There is always dead time to avoid shoot-through during HSFET/LSFET turn-on/turn-off.
