Question

How will you find out minimum value of inductance required to maintain continuous current given the values of load resistance, vout and vin? In buck-boost converter

Answer 1

• Real Buck or Boost operation with automatic and

seamless transition between Buck and Boost

operation

• 2.3V to 5.5V input voltage range

• 1.5A Continuous Output Current : VIN≥ 2.5V,

VOUT= 3.3V

• Adjustable and fixed output voltage

• Efficiency up to 95% in Buck or Boost mode and

up to 97% when VIN=VOUT

• 2.5MHz typical switching frequency

• 35μA operating quiescent current

• Integrated Soft –Start

• Power Save Mode

• True shutdown function

• Output capacitor discharge function

• Over-Temperature Protection and Over current

Protection

• Wide capacitance selection

• Small 1.766 mm x 2.086mm, 20-pin WCSP
