Description
General part information
AP3008 Series
The AP3008 is a 1.2MHz PWM boost switching regulator designed for constant-current white °C driver applications. The AP3008 can drive a string of 2 to 3 white °Cs from a 2.7V supply 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 also saves board space by reducing external component sizes. To improve efficiency, the feedback voltage is set to 95mV, which reduces the power dissipation in the current setting resistor. The AP3008 is equipped with OVP protection ability, the SW pin monitors the output voltage and will turn off the device if an over-voltage condition is present to prevent damage from an open circuit condition.
