3. VOUT = Output voltage of the boost converter. It is equal to the sum of VFB and the voltage drop across
LEDs.

Where:
1. IPP = inductor peak to peak ripple
2. L = inductor value
3. fs = switching frequency
(5)
Where:
1. IOUT(MAX) = maximum output current of the boost converter
2. ILIM = over current limit
3. h = efficiency
For instance, for VIN = 3 V, 7 LEDs output equivalent to VOUT of 23 V, an inductor value of 22 H, a current limit
of 700 mA, and an efficiency of 85%, the maximum output current is ~65 mA.
CHARGE MODE OPERATION
For current limited power source, such as a USB host or hub, the high efficiency converter is critical in fully
utilizing the input power capacity and quickly charging the battery. Due to the high efficiency in a wide range of
the input voltage and battery voltage, the switching mode charger is a good choice for high speed charging with
less power loss and better thermal management.
The TPS65200 is a highly integrated synchronous switch-mode charger with reverse boost function for USB
OTG support, featuring integrated MOSFETs and small external components, targeted at extremely space-limited
portable applications powered by 1-cell Li-ion or Li-polymer battery pack.
