The AP3152 is a high efficiency charge-pump white LED driver
with 1x, 1.5x, 2x operating modes. The AP3152 operates on
power supplies from 2.7v to 5.5v. It drives up to four channels of
white LEDs while the intensity of each channel is configured by
varying the respective current levels. Each channel can supply up
to 30mA current. Up to four channels can be ganged together to
provide maximum load current of 120mA.
The Serial Digital Interface (SDI) provides the capability to
configure the current for each LED channel. Some other key
features, such as Up Spread Spectrum Control, different
charge-pump switching frequencies (0.6MHz/1.2MHz/1.8MHz),
and PWM dimming control, can also be programmed through the
interface.
The AP3152 has a built-in soft-start circuit to minimize the inrush
current during power-up and mode switching. Various protections
such as short-circuit, over-voltage, under-voltage, and thermal
shutdown are integrated to ensure system reliability. The
quiescent current of AP3152 during shutdown is less than 1 μ A.
