Press Release Summary:
Delivering up to 500 mA, Model LTM8021 µModule(TM) regulates output voltage from 0.8-5 V that is adjusted with only one resistor. It includes dc/dc controller IC, power switch, on-board inductor, compensation circuitry, and I/O bypass capacitors. Available in 6.25 x 11.25 x 2.8 mm surface-mount LGA package, low profile and light weight (0.49g) enable system designers to solder device on backside of circuit board. RoHS compliant device operates from -40 to 85°C.
Original Press Release:
3VIN to 36VIN, 500mA DC/DC Switchmode µModule Regulator in Tiny Package Creates Space by Mounting on the Back of Board
MILPITAS, CA - May 29, 2008 - Linear Technology Corporation introduces the LTM8021, a complete DC/DC µModule(TM) regulator point-of-load (POL) system with on-board inductor and power components in a package that resembles a surface-mount IC. The LTM8021 operates from input supplies from 3V to 36V (40Vmax) and delivers up to 500mA. The LTM8021's tiny footprint (6.25mm x 11.25mm), low profile (2.8mm) and light weight (0.49g), enable system designers to solder the device on the backside of the circuit board, creating room on top for digital ICs such as FPGAs, memory and passives including HDMI, Ethernet or SMA connectors.
The LTM8021 includes a DC/DC controller IC, power switch, inductor, compensation circuitry and input and output bypass capacitors. Its design is as simple as a linear regulator and has the advantage of less heat dissipation and smaller size. Target applications are systems with 5V, 12V, 24V and 28V input supply rails such as medical, industrial, avionics and after-market automotive.
The LTM8021 regulates an output voltage from 0.8V to 5V that is adjusted with only one resistor. Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors, thus improving the reliability of the solution. The LTM8021 is rated for operation from -40°C to 85°C and is ROHS compliant, although its gold-plated pads enable use of Pb- and Pb-free solder during board assembly. 1,000-piece pricing starts at $5.85.
