CJ9220 2A, 1.5MHz Synchronous Step-Down DC-DC Converter
The CJ92209 is a high-efficiency, DC to DC step-down switching regulator, capable of delivering up to 2A of output current. The input and output range of CJ9220 is from 2.7V to 5.5V and 0.6V to VIN, making it suitable for low voltage power conversion.
Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR
inductors, thereby achieving higher efficiencies. Other external compon- ents, such as ceramic
input and output caps, can also be small due to higher switching frequency,while maintaining ex-
ceptional low noise output voltages. Internal soft-start control circui reduces inrush current.
■ FEATURES:
● Wide Input Voltage Range: :2.7~5.5V
● up to 2A max Output Current
● High Efficiency: up to 96%
● 1.5MHz Frequency
● 100% Duty Operation
● Internal Compensation
● SOT-23-5L Package
