monolithic regulator 26 deliver 25A at 12V from
inputs to 60V 28 The rapid expansion of constant-current/constant-voltage (CC-CV)
applications, especially in LED lighting and high capacity battery
and supercapacitor chargers challenges power supply designers to
keep pace with the increasingly complicated interplay of current and
voltage control loops. A switch-mode converter designed specifically
for CC-CV offers a clear advantage,
especially when the supply has limited
power, or its power is allocated
among several competing loads. The LTC4155 is a monolithic switching battery charger that efficiently delivers
3.5A charge current in a compact PCB footprint. See page 13.

supercapacitor in a minimum amount of time from
a power-limited supply. To maintain constant input

design features LED Controller with Dual Current Regulation Loops Detects
Faulty LEDs, Provides 100:1 Analog Dimming
Xin (Shin) Qi The LT3796-1 is a switching controller designed to
regulate a constant current or constant voltage at the
outputвЂ”necessary requirements for driving LEDs. It uniquely
features two independent current sense amplifiers, and its
high side PMOS disconnect switch driver, which can be
operated either in combination with the switching regulator
using the PWM pin or independently using the TGEN pin.
These features allow the LT3796-1
to satisfy the needs of some specific
LED applications. For instance, in high
reliability lighting, the controller can be
configured to drive two LED strings in
parallel so that it is possible to detect a
single faulty LED in either string using the
other as a reference. Or, for applications VIN
8V TO 20V requiring accurate analog dimming,
the two current sense amplifiers can be
scaled to regulate the LED current at two
ranges, high and low, thereby extending the analog dimming capability of a
high power LED driver to 100:1, a tenfold
improvement over what is typically available using a single current control loop. …
