AAT2614数据手册集成电路（IC）的线性稳压器控制器规格书PDF

描述 Description

The AAT2614 is a multiple rail power management integrated circuit. It integrates a 600mA switching regulator and four fully integrated 300mA low dropout (LDO) regulators in a small Pb-free 3mm x 3mm, 20-pin TQFN package or in a 1.65mm x 1.65mm, 16-bump CSP-0.4 package making it ideal for space-constraint systems.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.
