  advertisement Reduce Component Count and Improve Efficiency in
  SLIC and RF Power Supplies – Design Note 282
  Tick Houk
  Introduction
  Nonisolated power supplies with negative output
  voltages require op amps and other “glue” circuitry in
  order to level-shift the feedback voltage to the error
  amplifier. In applications such as SLIC (subscriber line
  interface circuit) power supplies, this extra circuitry
  adds unwanted cost and requires more space on the
  PC board, with no increase in system performance. A Dual Output SLIC Supply With Simplified
  Feedback Using the LTC3704
  Figure 1 illustrates a dual output telecom power supply
  designed for use in subscriber line interface circuits
  or SLICs. The input to the SLIC power supply is some
  form of battery (lead-acid or lithium-ion, for example)
  so that extended talk-time can be provided to POTS
  (plain old telephone system) phones during an AC line
  failure (or rolling blackout). The output voltage is typically proportional to the distance the subscriber line
  runs from the local hub to a house or office, in order
  to compensate for the impedance of the loop. Multiple
  output supplies are used to supply groups of users at
  different distances from the hub. The LTC В®3704 is a high performance, single-ended …

  DESIGN FEATURES A High Performance, Single-Ended,
  No RSENSE Controller for Negative
  Output Supplies
  by Tick Houk
  Introduction
  The LTC3704 is a general-purpose,
  single-ended current-mode DC/DC
  controller IC that is optimized for use
  in negative output converter applications. Unlike traditional controllers,
  which are optimized for positive outputs, the LTC3704 has a negative
  feedback pin (NFB), which can be
  connected directly to a divider from
  the negative output to ground. This
  direct connection saves space and
  expense by eliminating the traditional
  glue circuitry normally required to
  level-shift the feedback signal above
  ground. The LTC3704 provides flexible, high performance operation in a
  small MS10 package.
  The LTC3704 takes advantage of
  Linear Technology Corporation’s proprietary No RSENSE™ technology by
  sensing the voltage across the power
  MOSFET, as shown in Figure 1. This …
