AAT2608A Eight-Channel LDO with DC/DC Converter
The AAT2608A is a member of Skyworks' Total Power Management IC (TPMIC™) product family. It contains an 800mA switching regulator and eight fully integrated 300mA low dropout (LDO) regulators in a small, Pb-free 28-pin 4mmx4mm TQFN package, making it ideal for space-constrained systems. The step-down converter is a monolithic synchronous converter with an integrated compensation network and 90% efficiency. It operates at 1.5MHz and uses a tiny 2.2μH inductor with a small 10μF output capacitor. At no load the switching converter quiescent current is 70μA. The 8 channel 300mA LDO regulator features low power consumption, low dropout, and high noise immunity from the input power supply. Each channel consumes a mere 30μA of current when enabled, features 250mV of dropout at 250mA, and 68dB of power supply rejection at 10kHz. Each channel uses a small 1μF output capacitor and 2.2μF input capacitor. 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) between 0.6V and 3.7V with 100mV increment and typical regulation accuracy is ±1%. The switcher has a separate input from the linear regulators, permitting post-regulation configuration of the LDO channels from the switcher’s output. Its output is externally programmable with external resistors. LDO1 and LDO2 share the same input voltage, as do LDO3 and LDO4, while LDO5 through LDO8 have their own independent input. The AAT2608A is a safe solution which integrates an over-current limit for each channel and over-thermal protection. The device is rated over a temperature range of -40°C to 85°C.
