Dual switching controller in 16-SOIC
The MAX624ISE: It accepts a 3V to 5.5V input and delivers a fixed 5V output from a single output channel — a common rail for PCMCIA converter applications where the host card's 3.3V or 5V bus needs a regulated 5V supply for the card interface.
Lifecycle and compliance check
Note the RoHS non-compliant status — this part is not lead-free. If your BOM requires RoHS compliance (e.g., for EU-market equipment under 2011/65/EU), a lead-free alternative or exemption documentation will be needed.
Sourcing and procurement
The 16-SOIC footprint is a standard JEDEC outline; the supplier device package is 16-SOIC, so the PCB land pattern follows the common MS-012 variation. No special thermal pad or exposed paddle — the die heat dissipates through the leads and the board copper.
