In this series, there are two types of converters, ATI2202 and ATI2301.

ATI2202 is a 350 kHz fixed frequency PWM synchronous step-down regulator. The ATI2202 is operated from 4.75V to 23V, the generated output is adjustable from 0.923V to 18V, and the output current can be up to 2A.

1. Input Voltage Range: 4.75V ~ 23V

2. Output Voltage Adjustable Range: 0.923V ~ 18V

3. Output Current up to 2A

4. Efficiency up to 93%

5. Programmable Soft Start

6. Over Current Protection

7. Over Temperature Protection

8. RoHS Compliant and 100% Lead (Pb) Free

9. Fixed Frequency: 350 kHz

The ATI2301 is a step-down current-mode, DC-DC converter. At heavy load, it works at the constant frequency PWM mode which has good stability and transient response. To ensure the longest battery life under light load in portable applications, the ATI2301 features a power-saving pulse-skipping modulation (PSM) mode, which reduces quiescent current to save power.

1. High Efficiency: up to 96%

2. Internal Synchronous Rectifier

3. High Switching Frequency: 1.5MHz

4. Under-Voltage Lockout

5. Soft Start

6. Short Circuit Protection
