RFQ ListingPower Management ICs
LTM4644IY is an Analog Devices LTM4644 quad-output step-down (buck) uModule regulator — complete DC/DC with integrated controllers, MOSFETs, inductors and support components, supplied in a 77-lead BGA, 9 m 15 × 5.01 mm; tray (SnPb (63/37) finish). It operates from 4 V to 14 V (2.375 V to 14 V with external bias) with 0.6 V to 5.5 V, adjustable (each output) output, delivers 4 A per output (up to 16 A paralleled); 5 A peak per channel, switches at 1 MHz; external synchronization within ±30% of set frequency, and integrates the controller, power devices, inductor(s) and support components in one package.
