General Description
The AP3008 is a 1.2MHz PWM boost switching regulator
designed for constant-current white LED driver
applications.
The AP3008 can drive a string of up to 4 white LEDs
in series, ensuring uniform brightness and eliminating
several ballast resistors. The AP3008 implements a
constant frequency 1.2MHz PWM control scheme.
The high frequency PWM operation saves board space
by reducing external component sizes. A low 95mV
feedback voltage minimizes power loss in the current
setting resistor for better efficiency.
The AP3008 is equipped with OVP protection ability,
the SW pin monitors the output voltage and will turn
off the device if an overvoltage condition is present to
prevent damage from an open circuit condition.
The AP3008 is available in SOT-23-5 package.
