The Texas Instruments LM2796TLX is a charge-pump based white LED driver ideal for mobile phone display backlighting. It can drive up to 7 LEDs in parallel, each with up to 20mA. The LEDs are controlled in two distinct groups, suitable for backlighting main and sub-LCD displays. This device offers excellent current and brightness matching between LEDs due to regulated internal current sources.
Key electrical specifications include an input voltage range of 2.7V to 5.5V and an output voltage range of 2.7V to 5.5V. It operates with a maximum switching frequency of 675kHz and a maximum duty cycle of 100%. The driver supports direct PWM dimming with a frequency range of 100Hz to 1kHz. Peak efficiency is rated at 80% with a boost topology.
The LM2796TLX operates within a temperature range of -30°C to 85°C. It is housed in an 18-bump thin DSBGA package measuring 2.1mm x 2.4mm x 0.6mm, making it suitable for space-constrained designs. The device is designed for high-efficiency operation using a 3/2x charge pump.
The LM2796TLX operates with an input and output voltage range of 2.7V to 5.5V.
The LM2796TLX is packaged in a DSBGA (YZR) case measuring 2.1mm x 2.4mm x 0.6mm.
The device functions reliably within an operating temperature range of -30°C to 85°C.
The LM2796TLX supports seven independent LED channels.
Each channel can deliver a maximum LED current of 20mA.
