18V 100mA Step-Up Converter
General Description
Features
SwitchReg™
The AAT1230 is a high frequency, high efficiency
boost converter capable of 18V maximum output
• VIN Range: 2.7V to 5.5V
• Maximum Output: 18V @ 100mA
voltage. The internal power switch can deliver
• True Load Disconnect
100mA load current. It is the ideal power solution to

• Hysteretic Control
ing from a single cell lithium-ion battery.
— No External Compensation Components
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.
— Excellent Load Transient Response
— High Efficiency at Light Load
• Up to 2MHz Switching Frequency
• Ultra-Small Inductor and Capacitors
• Integrated Low RDS(ON) MOSFET Switches
• Up to 85% Efficiency
• <1µA Shutdown Current
• Integrated Soft Start
• Cycle-by-Cycle Current Limit
• Short-Circuit, Over-Temperature Protection
The output voltage can be dynamically set by acti-
