(1%) for r2, and determine r1 with : ? ? ? ? ? ? ? ? ? = fb fb out v v v 2 r 1 r for example, for a 1.1 v output voltage, r2 is 1k , and r1 is 3 7 4 . you can select a standard 3 74 ( 1%) resistor for r1. power dissipation the power dissipation for any package depends on the thermal resistance of the case and circuit board, the temperature differential between the junction and ambient air, and the rate of air fl ow. the power dissipation across the device can be represented by the equation: ( ) out out in i v v p ? = the allowable power dissipation can be calculated using the following equation: ( ) ja ambient junction (max) t t p ? = / where (t junction ? t ambient ) is the temperature differen tial between the junction and the surrounding environment, ja is the thermal resistance from the junction to the ambient environment. connecting the exposed gnd pad to a large ground pad or plane helps to channel away heat . output capacitor sele ction the mpq20056 is specifically designed to work with a stand ard ceramic output capacitor to save space and improve performance. use a 4.7f ceramic capacitor for most application s. larger output capacitor s will improve load transient response and reduc e noise at the cost of increased size.
