DESCRIPTION
Features
The A7501 Series is a CMOS VFM-control step-up
- Low voltage operation: Start up at 0.9V min switching regulator that mainly consists of a reference
(IOUT=1mA) guaranteed voltage source, an oscillator, and a parator.
- Low input current: During maximum operation:
Enabling products with a low ripple over a wide range, high efficiency, and high output current.
- 18μA (VOUT=3.3V, typ.) Duty ratio: 77% Built-in fixed-type PFM
Products with a fixed duty ratio of 75 %（Lower Output controller
Voltage）or 88%(Higher Output...
