WHITE / BLUE LED DRIVER FOR LI- ION BATTERY APPLICATION

POWER DISSIPATION TABLE

TYPICAL APPLICATION

ABSOLUTE MAXIMUM RATINGS

Note:

Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.

Currents are positive into, negative out of the specified terminal.

Note:

Junction Temperature Calculation; TJ = TA+(PD* θJA)

PD: Power Dissipation, TA: Ambient termperature, θJA : Thermal Resistance-Junction to Ambient

The θJA numbers are guidelines for the thermal performance of the device/PC-board system.

All of the above assume no ambient airflow.
