  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). …
