  advertisement “LCD Bias” and “Backup Supply” Applications for the
  LT1316 Micropower DC/DC Converter – Design Note 166
  Gary Shockey and Jeff Witt
  Some step-up DC/DC converter functions require input
  current limiting because of high source impedance or
  limited capability of power components. The LT В®1316, a
  micropower step-up DC/DC converter with peak switch
  current control, meets these needs. The device draws
  33ОјA quiescent current and contains a 0.6О©, 30V
  switch that can be programmed for a maximum peak
  current between 30mA and 600mA with an external
  resistor. It also has a low-battery detector that remains
  active in shutdown, where quiescent current drops to
  3ОјA. The two circuit examples below illustrate how
  the LT1316’s current limit function allows realization
  of difficult converter circuits.
  2-Cell, Low Profile LCD Bias Generator Fits in
  Small Places
  Portable electronic products with LCDs are getting
  thinner, resulting in severe restrictions on component
  height. LCD bias generators placed in or near the
  display housing need to use low profile (under 2mm)
  components to meet height restrictions. These low …
