Product details

The LT1932ES6#TRMPBF is a DC-DC regulator configured as a step-up (boost) LED driver with PWM dimming capability, designed primarily for backlight applications. It integrates the switching transistor internally, so the external BOM stays small — just the inductor, diode, and a couple of capacitors. The single channel delivers up to 40 mA, typical for small-to-medium backlight panels; if you need more current per string, this is not the part. The wide input range from 1 V to 10 V covers single-cell alkaline, Li-Ion, or regulated supplies. The TSOT-23-6 package is a surface-mount footprint that reflows easily in standard SMT lines.

ROHS3 compliant, no exemption issues for EU markets. For dual-sourcing resilience, the closest functional peer is the LT1937ES5#TRMPBF: same 1.2 MHz boost topology, same backlight application, but it offers both analog and PWM dimming and delivers 320 mA per channel — a different current tier.

Frequently asked questions

What are the alternatives to LT1932ES6#TRMPBF?

The LT1932ES6#TRPBF is a direct drop-in replacement — same die, same TSOT-23-6 package, same electrical ratings — differing only in reel format. For a higher-current option, the LT1937ES5#TRMPBF delivers 320 mA per channel with both analog and PWM dimming, but it comes in an SOT-23-5 package and has a 2.5 V minimum supply voltage, so it is not pin-compatible.

Can LT1932ES6#TRMPBF drive 10 LEDs in series?

Yes, the 36 V output is sufficient for ten white LEDs in series (typically 3.2 V forward drop each = 32 V, plus headroom for the current-sense resistor). The 40 mA per channel limit means each LED in the string shares that current; it is a single-string driver, not a multi-string array controller.

What is the LT1932ES6#TRMPBF datasheet?

The datasheet is published by Analog Devices under the LT1932 product family. It contains the full electrical characteristics, application circuits, inductor selection guide, and PCB layout recommendations. The datasheet is available for download from the manufacturer's website or through standard distributor portals.
