3 / 45 page LM3630A www.ti.com SNVS974 – APRIL 2013 PIN DESCRIPTIONS Ball Name Description A1 SDA Serial Data Connection for I2C-Compatible Interface A2 SCL Serial Clock Connection for I2C-Compatible Interface A3 SW Inductor Connection, Diode Anode Connection, and Drain Connection for Internal NFET. Connect the inductor and diode as close as possible to SW to reduce inductance and capacitive coupling to nearby traces. B1 HWEN Logic High Hardware Enable B2 INTN Interrupt output for fault status change. Open drain active low signal. B3 GND Ground C1 PWM External PWM Brightness Control Input C2 SEL Selects I2C-compatible address. Ground selects 7-bit address 36h. VIN selects address 38h. C3 IN Input Voltage Connection. Connect a 2.3V to 5.5V supply to IN and bypass to GND with a 2.2 µF or greater ceramic capacitor. D1 OVP Output Voltage Sense Connection for Over Voltage Sensing. Connect OVP to the positive terminal of the output capacitor. D2 ILED2 Input Terminal to Internal Current Sink #2. D3 ILED1 Input Terminal to Internal Current Sink #1. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
