Applications
LTM4644IY#PBF is a quad-output DC/DC µModule (up to 4 A per channel) in a 77-ball BGA. Input 4–14 V, output 0.6–5.5 V adjustable, industrial I-grade (-40 to +125°C) are the usual BOM locks.
Procurement notes
RFQ the exact ADI orderable including #PBF. E-grade (EY) or non-PBF reel codes are potential alternatives / require engineering validation of temperature and solder process, not a silent AVL swap.

FAQ
Is LTM4644IY currently available?
Availability is shown on this product page from live inventory and changes as lots move. Submit an RFQ with quantity and required date so SJ Chip can confirm remaining stock, date code, and lead time before you issue a PO.
Can LTM4644IY be replaced by LTM4644EY#PBF?
LTM4644EY#PBF may be a potential alternative / requires engineering validation (pinout, firmware, clocks, power, and errata). It is not a direct replacement. Do not change the AVL until the customer's engineering team approves the evaluation.
Is this a drop-in replacement?
No. SJ Chip does not list parts as drop-in or direct replacements. Any nearby MPN is a potential alternative / requires engineering validation before production use.
How can I request a quotation?
Open https://www.sj-chip.com/rfq, enter the full part number, quantity, and required date. The sourcing team replies within 24 working hours with availability, condition, and lead time on the quotation.
Is LTM4644EY#PBF the same as LTM4644IY#PBF?
E vs I is a temperature grade. Do not mix grades on an industrial AVL without thermal qualification. It is not a direct replacement.
