Active-production boost driver for small-panel backlights
The TPS61151DRCT: Rated for 27 V output at 35 mA per channel, it powers the backlight in portable instruments, handheld scanners, and automotive-cabin displays where the input bus is 2.5 V to 6 V. The 1.2 MHz switching frequency keeps the external inductor and output capacitor small enough to fit alongside the 10-VSON (3 × 3 mm) package on a two-layer board.
PWM dimming with two independent channels
Two outputs with PWM dimming let the designer control each LED string's brightness independently — useful for dual-display handhelds or split-panel automotive clusters where one string may need a different luminance setting. The internal switch handles the full 35 mA per channel, so no external FET is needed; the boost topology steps the input up to 27 V even when the battery has dropped to 2.5 V.
Compliance and supply posture
ROHS3 compliant — no exemption restrictions for EU or California market entry, and no REACH SVHC declaration issues for the bill of materials.
