3 / 13 page SAMHOP Microelectronics Corp. 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.
