Original Press Release:
AnalogicTech Announces New 24V, 100mA Boost Converter with Dynamic Output Voltage Programming
Space-Efficient Packaging and Few External Components Minimize System Footprint
SUNNYVALE, Calif., Aug. 28 // -- Advanced Analogic Technologies Incorporated (AnalogicTech) (NASDAQ:AATI), a developer of power management semiconductors for mobile consumer electronic devices, today announced the AAT1232, a 24V, 100mA boost converter for portable products powered by single-cell Lithium-ion batteries. This new addition to AnalogicTech's rapidly growing family of boost converters is targeted primarily at cost-sensitive OLED, LCD, and CCD applications, and offers substantial output drive capability in an extremely compact footprint.
"Lighting and display functions, while operating, can consume a significant portion of a Lithium-ion battery's available power," explains Adolfo Garcia, Product Line Director for AnalogicTech. "Finding ways to optimize power dissipation and maintain display quality brings real value to the customer's application. The AAT1232 boost converter is tailor-made for these cost-sensitive applications by combining output voltage programming with high output current drive in space-efficient packaging."
Minimizing PCB Footprint
Operating at a switching frequency up to 2MHz, the AAT1232 reduces PCB footprint by using small-value external inductors and capacitors. For example, the AAT1232 operates with 2.2uH inductors that are approximately ten times smaller than many competitive boost conductors require. Small TSOP and TDFN packages and fewer external components also help reduce system cost.
Configuring the AAT1232's operation is easy and dynamic. Depending on the application, the system designer can select one of two internal feedback reference voltages using its SEL input. In addition, the AAT1232 offers dynamic output voltage programming over a 16-step range using the company's patented single-wire S(2)Cwire(TM) (Simple Serial Control(TM)) interface, a lower cost and simpler alternative to traditional I2C-based addressing/programming methods.
A True Load Disconnect feature on the AAT1232 completely isolates the load from the power sources when the EN/SET input is pulled low. This feature helps to minimize standby power dissipation and extends battery life by virtually eliminating leakage current. The AAT1232 maintains 80% efficiency across a wide range of load currents -- even down to 1mA.
This new boost converter also features a number of protection circuits, including integrated soft start, cycle-by-cycle current limit, and short-circuit protection.
Price and Availability
The AAT1232 is available now in a Pb-free, 16-pin, 3x4mm TDFN package or a Pb-free, 12-pin TSOPJW package. The device is specified over the -40 degrees C to +85 degrees C operating temperature range and sells for $1.05 each in 1,000-unit quantities.
