Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through
correlation using statistical quality control (SQC) methods.
Note 2: Input withstand voltage. Not designed to operate above VDC = 6.5V due to thermal-dissipation issues.
Note 3: ISET voltage when CT timer stops. Occurs only when in constant-current mode. Translates to 20% of fast-charge current.
Note 4: Temperature at which the input current limit begins to reduce.
Note 5: The WLED driver’s sink current ramp time is a function of the external compensation at CC3. With a compensation of 1kΩ in
series with 0.22µF and a target sink current of 30mA, the WLED boost’s output voltage ramps up in 1.25ms, but the WLED
sink current of 30mA settles in 12ms. See the OUT3 Enable and Disable Response graph in the Typical Operating
Characteristics section for more information.
