DC to DC Power Supplies (Converters)
DC/DC Point-of-Load Regulator has heat-dissipating design.
Press Release Summary:
Supplied in 6.25 x 6.25 x 2.3 mm LGA SMT package, LTM8020 DC/DC uModule(TM) regulator system includes DC/DC controller IC, power switches, inductor, compensation circuitry, as well as input and output bypass capacitors. It offers switch-mode topology and does not require heatsink. This 200 mA, current mode, switching DC/DC point-of-load regulator system can be mounted on back side of circuit board, accepts input from 4-36 V, and offers adjustable output from 1.25-5 V.
Original Press Release:
36V(IN), 200mA DC/DC uModule Regulator Is as Simple as a Linear Regulator but with 98% Less Heat Dissipation and 190% Smaller Design Without Hot Spots
36VIN, 200mA DC/DC uModule Regulator Is as Simple as a Linear Regulator But with 98% Less Heat Dissipation and 190% Smaller Design
MILPITAS, CA - October 29, 2007 - Linear Technology Corporation introduces the LTM8020, the first in a new family of DC/DC uModule(TM) regulator systems that operate from higher voltage input supplies of up to 36V (40Vmax). The LTM8020 is a 200mA complete DC/DC solution that includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors. This solution is extremely compact at only 6.25mm x 6.25mm and low profile at 2.3mm in height. Compared to a linear regulator circuit, the LTM8020's more efficient switch-mode topology provides cooler operation, dissipating 98% less heat and occupying 190% less volume (area x height) with its compact package and no-heatsink requirement (comparison conditions: 36VIN, 1.5VOUT, 200mA, TA=25ºC). Target applications are systems with 24V and 28V input supply rails such as medical, industrial, avionics and after-market automotive.
The LTM8020 is a complete 200mA, current mode, switching DC/DC point-of-load regulator system in a 6.25mm x 6.25mm x 2.3mm LGA (Land Grid Array) surface-mount package. The package can be mounted on the back side of a circuit board, allowing more room for digital ICs on the top side. Input voltage range is from 4V to 36V and output can be adjusted with only one resistor from 1.25V to 5V. Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors, thus improving the reliability of the design. The LTM8020 is rated for operation from -40ºC to 85ºC and is ROHS compliant. Its gold-plated pads allow both Pb- and Pb-free solder to be used during board assembly.
1,000-piece pricing starts at $4.95 each.
