QUICK START GUIDE
The output voltage on this board is preset to 4.2V (for a single cell battery). The board layout
accommodates most commonly used capacitors.
The LEDs are power indicators. When LED1 is on, the 5V input and Enable High (>2.8V) are present
(LED1 is off when the input is disconnected). When LED2 is on, the battery is charging, and when the
battery is full or there is no battery connected, LED 2 will turn off.
1. Set the charge current I
CHG
using the jumpers JP1, JP2 and JP3 per the following table:

2. Attach the positive and negative ends of the load to the VOUT and GND pins, respectively.
3. Attach the input voltage (V
IN
=5V) and the input ground to the VIN and GND pins, respectively.
4. The timer cap, C5 on EVB is 2.2µF. This will set the oscillator frequency to be 5Hz. For different
oscillator frequency setting, please follow the formula:
