3VIN to 36VIN, 500mA DC/DC Switchmode uModule Regulator in Tiny Package Creates Space by Mounting on the Back of Board

Linear Technology Corporation introduces the LTM8021, a complete DC/DC uModule™ 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 ouwtput bypass capacitors.

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.
