Fremont, Calif.Exar Corp. has introduced a synchronous inductive step-down converter dubbed the SP6669, which is capable of delivering up to 600mA, and achieving output voltages as low as 0.6V.
The device is well-suited for portable devices with a USB interface, including digital cameras, portable media players, and wireless networking amongst others.
Operating at a fixed internal switching frequency of 1.5MHz, the SP6669 can reach 95% efficiency. Its output voltage can be set as low as 0.6V or 1.5V and 1.8V for the fixed output versions, which can be achieved from any input voltages from 2.5V to 5.5V. This synchronous converter offers tight 0.4%/V and 0.5% of line and load regulations.
Pricing: In 1,000-piece quantities in a SOT-23-5 package, the SP6669 is $0.49.
Availability: Samples are available now in a -40°C to +85°C temperature range.
