AAT1230

18V 100mA Step-Up Converter General Description The AAT1230 is a high frequency, high efficiency boost converter capable of 18V maximum output voltage. The internal power switch can deliver 100mA load current. It is the ideal power solution to power OLED, LCD, and CCD applications operating from a single cell lithium-ion battery. Hysteretic control provides up to 2MHz switching frequency and fast response to load transients with small, low-cost external components. The fully integrated control IC simplifies the design while reducing the total PCB footprint. The AAT1230 offers a true load disconnect feature which isolates the load from the power source when EN/SET is pulled low. This eliminates leakage current and maintains zero voltage at the output while disabled. AAT1230 Features SwitchReg™ The output voltage can be dynamically set by activating one of two reference levels (FB1 or FB2) through the SEL logic pin. Optionally, AnalogicTech’s Simple Serial Control™ (S2Cwire™) single wire interface provides dynamic programmability across a wide output voltage range through the EN/SETwww.DataSheet4U.com pin. The AAT1230 is available in a Pb-free, thermallyenhanced 16-pin 3x4mm TDFN low-profile package or a Pb-free 12-pin TSOPJW package. VIN Range: 2.7V to 5.5V Maximum Output: 18V @ 100mA True Load Disconnect Dynamic Voltage Control Options Hysteretic Control — No External Compensation Components — Excellent Load Transient Response...
