  Bidirectional Switching Power
  Imagine that your car won’t start—the Path for USB On-The-Go by Sauparna Das Introduction 5.5 The LTC4160 contains a bidirectional
  switching regulator between VBUS
  and VOUT. When power is applied to
  VBUS,the switching regulator acts as
  a step down converter and provides
  power to the application and battery
  charger (Figure 1). The switching
  regulator includes a precision average
  input current limit with multiple settings. Two of the settings correspond to
  the USB 100mA and 500mA limits. The bidirectional switching
  regulator is able to power a
  portable system and charge
  its battery or provide a 5V
  output for USB On-The-Go
  using a single inductor.
  The voltage on VOUT is approximately 300mV above the battery when the
  switcher is not in input current limit
  and the battery voltage is above 3.3V.
  This technique, known as Bat-Track …
