PRODUCTION DATA
The input capacitor buffers the input voltage for transient events and decouples the converter from the supply. TI recommends a 2.2-µF input capacitor across the VIN pin and PGND placed close to the device, and connected using wide traces. X7R-rated ceramic capacitors are the best choice due to the low ESR, high ripple current rating, and good temperature performance. Additional capacitance can be required to further limit the input voltage deviation during PWM dimming operation.
