LTM8021
ACAL Technology has introduced Linear's LTM8021 DC/DC uModule regulator point-of-load (POL) system with on-board inductor and power components.
It comes in a package that resembles a surface-mount IC.
The LTM8021 operates from input supplies from 3 - 36V (40V maximum) and delivers up to 500mA.
The LTM8021's tiny footprint (6.25 x 11.25mm), low profile (2.8mm) and light weight (0.49g) enable systems-designers to solder the device on the back 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 0.8 - 5V that is adjusted with only one resistor.
Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors.
The LTM8021 is rated for operation from -40C to +85C and is ROHS compliant.
Its gold-plated pads enable use of leaded and lead-free solder during board assembly.
