AAT2614 Compact Integrated 600mA Switching Converter with 4-Channel 300mA LDO Regulator

The step-down converter is a monolithic synchronous converter, which integrates its compensation network and features up to 90% efficiency. It operates at 2MHz and uses a tiny 2.2μH inductor with a small 10μF output capacitor. At no load, AAT2614 current consumption is typically equal to 260μA. Each LDO operates with a small 1μF output capacitor and only two 2.2μF input capacitors are required for the inputs. All regulators include a separate enable providing a convenient solution to implement any power-up and power-down sequencing. All output voltages are factory One Time Programmable (OTP). The typical regulation accuracy is +/-1% for all channels. With their separate inputs the linear regulators can use the switcher’s output as their input power, in order to reduce drop out voltage and improve efficiency.

AAT2614 is a safe solution, which integrates an over-current limit for each channel and over-temperature protection. The device is rated over a temperature range of -40°C to 85°C.
