Multi-Chemistry Battery Charger Supports Maximum Power
Point Tracking for Solar Panels
Trevor Barcelo The LTC4015 is a versatile synchronous step-down charger capable of supporting a variety
of battery chemistries including lead-acid, Li-ion and LiFePO4. The LTC4015 features an
extensive list of battery charging functions, including coulomb counting and an array of
battery and system monitor capabilities. However, this article focuses on its input control
loop, which enables solar panel maximum power point tracking (MPPT) functionality.
For readers who have not yet encountered the general concept of MPPT, or
could use a knowledge refresh, visit
www.linear.com/solutions/4545. Regardless
of your general knowledge of MPPT, to
understand the LTC4015вЂ™s implementation, it is important to understand the
LTC4015вЂ™s multi-control-loop operation.
BASIC DEVICE OPERATION The LTC4015 charges batteries with a
peak current mode synchronous stepdown controller driving MN2 and MN3
(see Figure 1). The controller can regulate
four parameters: input voltage (using
the UVCLFB pin), input current (CLP and
CLN), battery charge voltage (BATSENS)
and battery charge current (CSP and
CSN). Both peak inductor current control
and battery charge current regulation
are accomplished with sense resistor …
