GENERAL DESCRIPTION
FEATURES
designed for driving single or multiple series connected LED efficiently from a voltage source
higher than the total LED chain voltage. The device operates from an input supply between
8V and 32V and provides an externally adjustable output current of up to 1A. Depending
upon the supply voltage and external components, the APE1630 can provide more than 15
watts of output power. The APE1630 includes the power switch and a high-side output
current sensing circuit, which uses an external resistor to set the nominal average output
current, and a dedicated DIM input accepts a wide range of pulsed dimming. Applying a
voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a
low current standby state.

... The APE1630 allow dimming with a PWM signal at the DIM input. A logic level below 0.3V at DIM forces APE1630 to turn off the LED and the logic level at DIM must be at least 2.0V to turn on the full LED current. The frequency of PWM dimming ranges from 100Hz to more than 20 kHz. The DIM pin is pulled high current approximately 70µ ...

... LED color does not vary with brightness as it does with analog dimming. Pulsing the current provides precise brightness control while preserving the color purity. The dimming frequency of APE1630 can be as high as 20 kHz. Shutdown mode Taking the DIM pin to a voltage below 0.3V will turn off the output and the supply current will fall to a low standby level of 70µ ...

... Inductor selection Recommended inductor values for the APE1630 are in the range 47uH to 120uH. Higher values of inductance are recommended at lower output current in order to minimize errors due to switching delays, which result in increased ripple and lower efficiency. Higher values of inductance also result in a smaller change in output current over the supply voltage range ...

... This prevents the switch working with excessive 'on' resistance under conditions where the duty cycle is high. Thermal shutdown protection To ensure the reliability, the APE1630 is built with a thermal shutdown (TSD) protection function. The TSD protests the IC from over temperature (150°C). When the chip temperature decreases (115°C), the IC recovers again. ...
