That is a formal flag from TI: existing production continues but the part is no longer being designed into new products. For new designs, the prudent move is to evaluate a pin-compatible or functional replacement before the EOL notice arrives. ## 2-channel, 30 mA per string — split-display or dual-zone backlight Two independent output channels, each rated at 30 mA, let the TPS61162DYFFR drive separate LED strings for dual displays (e.g. a main and sub-display in a handheld device) or split a single backlight into independently dimmable zones. The 2.7 V minimum output voltage allows operation with a single LED, while the 27 V ceiling supports up to eight or nine white LEDs in series, depending on their forward voltage. ## Analog and PWM dimming on the same pin Both analog and PWM dimming are supported, giving the design engineer two brightness-control paths without extra pin overhead. Analog dimming adjusts the LED current linearly; PWM dimming modulates the on-time for wider contrast ratios. The 1.2 MHz switching frequency keeps the inductor small — a 4.7 µH to 10 µH part is typical — and places the switching harmonics well above the audio band. ## 9-DSBGA footprint — board-level handling Housed in a 9-bump DSBGA package (0.4 mm pitch, 1.5 mm × 1.5 mm body). The fine-pitch BGA demands a clean solder-paste stencil and a controlled reflow profile. Moisture sensitivity level (MSL) is not stated in this record, but DSBGA packages typically require bake before reflow if the floor-life has been exceeded. The small footprint suits space-constrained portable designs but makes manual rework impractical without a hot-air station and micro-scope.","metaTitle":"TPS61162DYFFR LED Driver, DC-DC Boost, 2-Ch 30mA, NRND","metaDescription":"Texas Instruments TPS61162DYFFR dual-channel white LED driver.
