说明
- Typical Application for ADP1621 Constant-Frequency, Current-Mode Step-Up DC/DC Controller. The input range for the demo board is 3V to 3.6V and the output voltage is 5V with a maximum load of 2A. The switching frequency fSW is set to 600 kHz with a 36 k-ohm resistor. This design is done in all multilayer ceramic capacitors (MLCC), although other types of capacitors can be used such as the aluminum polymer or aluminum electrolytic capacitors
