說明
-
Application circuit for AP3402 is a 2A step-down DC-DC converter. At heavy load, the constant frequency PWM control performs excellent stability and transient response. No external compensation components are required. The AP3402 supports a range of input voltages from 2.7 to 5.5V, allowing the use of a single Li+/Li- polymer cell, multiple Alkaline/NiMH cell, and other standard power sources. The output voltage is adjustable from 0.6V to the input voltage. The AP3402 employs internal power switch and synchronous rectifier to minimize external part count and realize high efficiency
