Active production — BOM-fit note
The MAX25511ATGA/V+: Qualified to AEC-Q100, the device is screened for automotive temperature and reliability stress, making it suitable for under-hood or cabin LED lighting modules that must pass PPAP documentation.
Boost regulator with four independent channels
The MAX25511ATGA/V+ is a step-up (boost) DC-DC regulator that drives up to four LED strings, each rated for 120 mA continuous output. The internal switch is integrated, so the external BOM is limited to the inductor, input/output capacitors, and current-setting resistors. Dimming is supported via analog or PWM control, giving the system designer flexibility to adjust brightness without changing the boost output voltage.
Supply range and switching frequency
The switching frequency is programmable from 400 kHz to 2.2 MHz, allowing the inductor and output capacitor to be sized for the target ripple and board area.
Package and thermal interface
The device is housed in a 24-WFQFN with an exposed pad (24-TQFN, 4 mm × 4 mm). Surface-mount assembly with MSL (moisture sensitivity level) per the manufacturer's label — the part ships in tube packaging, so the MSL rating should be verified against the reflow profile before stencil design.
