Analog Devices Unveils ADP3031 Synchronous Regulator
Analog Devices Inc. (Wilmington, MA) announced its new ADP3031, a 2MHz, step-up (boost), dc/dc switching regulator capable of up to a 12V output, and available in a space-saving MSOP-8 package. The high operating frequency allows small external components to be used, reducing space and cost. The device also provides high efficiency (greater than 90 percent), low-noise operation, and is easy to use. Operating within a 2.5V to 5.5V input range with an adjustable output that supports voltages down to 3V, the ADP3031 is flexible for many low- and high-voltage applications and battery-powered equipment.
Other features include the pulse-width modulation current-mode control technique, which enables dynamic response and ease of noise filtering; an integrated 1.5A power switch to reduce external component count; three-percent output regulation over line, load and temperature to increase system accuracy; a shutdown mode to reduce quiescent current and save battery life; current limit and under-voltage lockout for circuit protection; and a space-saving, surface-mount package to reduce solution footprint and cost.
The ADP3031 is priced at $2.06 each in 1,000-piece units, and operates within the -40 to +85 degrees C temperature range. Samples are presently available.
