Dual ВµModule DC/DC Regulator Produces High Efficiency
4A Outputs from a 4.5V to 26.5V Input
Design Note 474
Alan Chern
Dual System-in-a-Package Regulator
Systems and PC boards that use FPGAs and ASICs are
often very densely populated with components and ICs.
This dense real estate (especially the supporting circuitry
for FPGAs, such as DC/DC regulators) puts a burden on
system designers who aim to simplify layout, improve
performance and reduce component count. A new family of DC/DC ОјModule В® regulator systems with multiple
outputs is designed to dramatically reduce the number
of components and their associated costs. These regulators are designed to eliminate layout errors and to offer
a ready-made complete solution. Only a few external
components are needed since the switching controllers, power MOSFETs, inductors, compensation and other support components are all integrated within the compact
surface mount 15mm Г— 15mm Г— 2.82mm LGA package.
Such easy layout saves board space and design time by
implementing high density point-of-load regulators.
The LTMВ®4619 switching DC/DC ОјModule converter
regulates two 4A outputs from a single wide 4.5V to
26.5V input voltage range. Each output can be set between 0.8V and 5V with a single resistor. In fact, only a
few components are needed to build a complete circuit
(see Figure 2). …
