Description
The AP2201 Series is a CMOS PFM-control step-up switching regulator that mainly consists of a reference voltage source, an oscillator, and a comparator, enabling products with a low ripple over a wide range, high efficiency, and high output current.
Features
- z Low voltage operation: Startup at 0.9 V min (Iout 1 mA) guaranteed
z Low input current: 2.3uA (Vout 3.3 V)
z Duty ratio: 75 % Built-in fixed-type PFM controller z External parts: Coil, capacitor, and diode z Output voltage: Settable to between 1.5 to 6.0V
accuracy of 2%.
