General Description
The APW7500 is 1MHz buck converter with a 7-bit current DAC to provide a well regulated current source for IR_LED application. The APW7500 owns wide range input voltage is from 4.5V to 24V adjustment and 2 channels output current source for IR_LED, the current source can be from 100mA change to 800mA by I2C interface control. The APW7500 integrates protections such as over voltage, under voltage and current limit of buck converter output. The VLED1/2 has under voltage protection only. In addition; The APW7500 has over-temperature protection. When the buck converter output is overloaded or short circuited, the device limits the current at a safety level to prevent catastrophic failure. The over-temperature protection shuts down the device when junction temperature reaches 150oC and will automatically resume operating when junction temperature cools down by 30oC. The cathode of the flash LED is referenced to GND, which Improves thermal performance. The APW7500 is available in WLCSP1.42x1.52-12 package.

  • Available in WLCSP 1.42x1.42-9
  • Lead Free Green Devices Available (RoHS Compliant)

General Description
The APW7502A is a 5V/1.37A, 2MHz buck converter with a 7-bit current DAC to provide a well regulated current source for VCSEL and IR_LED applications. Through I2C interface, the start-up slew rate of the current source can be 8-segment adjustable and the regulated level can be adjusted too from 100mA to 1.37A in 10mA resolution. When the buck converter output is overloaded or short circuited, the device limits the current at a safety level to prevent catastrophic failure. The over-temperature protection shuts down the device when junction temperature reaches 150oC and will automatically resume operating when junction temperature cools down by 20oC. The cathode of the flash LED is referenced to GND, which improves thermal performance. The device is available in WLCSP 1.42x1.42-9 package.
