Switching regulators for
high current density
Analog Devices has expanded its switching regulator product portfolio with the 1A ADP3088 and 1.5A ADP3089 1MHz nonsynchronous buck switching regulators
Packaged in a 3 x 3mm, space-saving 8-pin chip scale package, the ADP3089 provides the best mA/mm ratio in the industry. The ADP3088, housed in a MSOP-8 package, works up to an 11V input with a 10.5V maximum output, and the ADP3089 works up to a 12V input with a 11.5V maximum output. Designed for battery-powered equipment and a variety of consumer, industrial, portable, computer and instrumentation applications, these switching regulators provide an accurate, stable, stepped-down regulated output voltage, and a cost-effective, efficient power solution.

A novel undersea pipeline monitoring system features multiple sensor nodes, each driven by a Blackfin processor
Other features include a high PWM mode operating frequency to reduce external component size and ease noise filtering; an integrated power switch to reduce external component count; 3% output regulation over line, load and temperature to increase system accuracy; power saving and shutdown modes to reduce quiescent current and save battery life; cycle-by-cycle current limiting for circuit protection; and space-saving packages to reduce solution footprint and cost.
Both switching regulators operate over the -40 to +85C temperature range.
The ADP3088 and ADP3089 are priced at $2.02 and $2.49, respectively, per unit in 1000 piece quantities, and both are available from stock.
