DC/DC Regulator Has 2.3mm Profile and Tiny Footprint

With a profile of only 2.3mm, the LTM4604 is specifically designed as a compact point-of-load DC/DC solution for applications requiring ultra-thin packaging such as RAID systems and single-board computers using PCI or PCI Express. Moreover, the compact size, low profile and light weight allow the LTM4604 to be mounted on the back side of a printed circuit board, freeing space on the top side for FPGAs, ASICs, memory and other ICs.

The LTM4604 is a complete, compact and high reliability DC/DC point-of-load solution for systems that need to step-down input supply rails such as 5V, 3.3V, 2.5V or Li-Ion battery with precise regulation and excellent thermal performance. The device features a current mode architecture for fast transient response, short-circuit protection and excellent line and load regulation. In addition, it offers output voltage tracking for controlled ramp-up/ramp-down and supply sequencing. Also included are a power-good output signal to indicate whether the output voltage is in or out of regulation and protection circuitry for short-circuit and overtemperature conditions.

The LTM4604 is rated for operation from -40°C to 85°C. The LTM4604 is RoHS compliant and like all Linear Technology DC/DC uModule regulators, can be assembled with a standard surface mount reflow process with Pb-based or Pb-free solder paste, 1,000-piece pricing is $8.95 each.
