4-Channel LDO PMIC for Camera Applications
  • SKU
    WL2866D
  • Category
    Power Management - LDO
  • Application
    Mobile Devices

The WL2866D is a 4-Ch integrated LDOs for camera sensor applications include 2-Ch DVDD, 2-Ch AVDD, With 400 KHz high speed I2C interface, the function setting is flexible such as power sequence, output voltage, output discharge. The chip enable control support EN pin control and I2C control.

Due to high load current and lower working voltage of DVDD, WL2866D used N-MOSFET LDO architecture without charge pump for 2-Ch DVDD LDO. DVDD LDO input source is VIN1 and VIN2 is the bias voltage. Ultra low dropout voltage (Typ.80 mV @ 0.5A Load) of DVDD LDOs is designed for high efficiency and lower power dissipation purpose. For the AVDD, WL2866D used P-MOSFET LDO architecture. The input source is VIN2. Due to high performance requirement of AVDD, WL2866D’s AVDD used special circuit design and optimized pin assignment which is easy for system PCB layout.   

Highly integrated, small package size. WL2866D is available in DFN2x2-10Lpackage. Standard products are Pb-free and halogen-free.

– Smart Phone
– IP Camera
