TPS82671: 600mA Fully Integrated Power Solution

The TPS82671 is the smallest fully integrated 600mA power solution in a 6.7 mm ^{2 package, delivering a current density of 90mA/mm 2.} The buck regulator incorporates all external components in the new TI microSiP™ - simplifying the design of portable electronics.

The converter offers greater than 90% efficiency from an input voltage of 2.3 V to 4.8 V while operating at a quiescent current as low as 17 µA. A unique PWM frequency dithering feature reduces noise and improves performance.
