  20A Power Supply Ensures Safe Charging of
  Supercaps and Li-Ion Batteries
  Josh Caldwell Many applications require a power supply that can
  accurately regulate a voltage and accurately limit output
  current, but there are remarkably few solutions that can
  do both with a single IC. System designers must typically
  trade off accuracy in one feature for accuracy in the
  other by choosing between a high gain, high accuracy
  voltage regulator with a crude current limit or a high
  accuracy current regulator with a crude voltage clamp. SINGLE-CELL LITHIUM-ION
  BATTERY CHARGER PROVIDES
  10A OF CHARGING CURRENT Safety concerns and thermal limitations
  of charging lithium-ion batteries mean
  the charger must be able to carefully
  control charging currents and voltages.
  Ideally, a microcontroller can accurately
  throttle back the charging current during
  the initial and top-off charging phases.
  This forces the use of a current regulation scheme that has precision adjustable
  current control, thermal limiting capabilities, and an accurate voltage limit. The LTВ®3741 simplifies the design of
  constant-current, constant-voltage regulators by combining an accurate current
  regulator and an accurate voltage regulator in a single IC, thus eliminating power …
