- 1.8-V input, adjustable output voltage and low-profile package delivers superior balance of performance and value for battery-powered industrial and consumer applications.

Norwood, MA (05/27/2009) - Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, has expanded its portfolio of power management products with two new low-voltage, step-up dc-to-dc converters. The products feature wide input-voltage support to enable highly efficient power management for portable consumer electronics, industrial and instrumentation applications. The ADP1612 and ADP1613 dc-to-dc converters enable designers to boost input voltages as low as 1.8 V up to output voltages as high as 20 V. This performance, combined with thin-profile packaging and high switching frequency operation, make the new dc-to-dc converters ideally suited to increase battery run times for portable industrial and consumer applications, such as TFT LCDs (thin film transistor liquid crystal display) or cell phones, where low power consumption is required and board space is at a premium.

“Portable systems designers are always searching for ways to improve battery life, while cost-effectively extending usage time and adhering to stringent size requirements,” said Laurence McGarry, marketing manager, Analog Devices. “Input voltage operation can have a significant impact on power consumption in portable systems. With this in mind, ADI designed the new ADP1612 and ADP1613 boost converters to manage input voltages starting at 1.8 V–compared with conventional devices that support only 2.0 V input and up–offering an excellent balance of performance and value for applications operating on 3.3-V to 12-V rails.”

Flexible Design Uses PWM Current-Mode Architecture
Supporting a broad input voltage range (1.8 V to 5.5 V for the ADP1612 and 2.5 V to 5.5 V for the ADP1613), an adjustable output voltage allows the new step-up converters to extend battery life with unregulated input voltage operation. The boost converters use a PWM (pulse-width modulation) current-mode architecture to regulate the output voltage across load conditions and to help reduce the risk of inrush currents at startup. As a result, the devices are able to deliver up to 93 percent efficiency with fast transient response and stable output voltage levels for greater system reliability.

The ADP1612 and ADP1613 also feature pin-selectable switching frequency, allowing them to operate at 650 kHz (kilohertz) for maximum efficiency or at 1.3 MHz (megahertz), which enables the use of smaller external passive components. Completing this new family of boost regulators is the ability to get new designs to market quickly by using Analog Devices’ SimPower design tool.

Availability and Pricing
Samples of the ADP1612 and ADP1613 boost converters are available now in low-profile, 8-lead MSOP (mini small outline package) packaging. Pricing for the ADP1612 is $1.50 per unit, and the ADP1613 is $1.20 per unit in 1,000-unit quantities.
