Sipex Corp. has released the SP4446 micropower boost regulator that is suitable for use in PDAs, digital cameras, and handheld electronic products. They offer a quiescent current of 20?A, and a standby current of 10nA.

An internal 150mA, 30V power switch allows input voltages of 1V to generate output voltages of 30V. Together with an SOT-23 package, the integrated power switch minimizes design footprint by eliminating the complex circuitry usually required in high voltage designs.

The product also has a current-limited, fixed off-time architecture that ensures consistent brightness when driving up to three white LEDs, and provides low ripple current for noise sensitive applications.

The SP4446 is available at 60 cents in 100,000 piece quantities. An evaluation board is also available to assist in the evaluation of the device.
