power dissipation
The power dissipated in the TPS6012x depends on output current and mode of operation (1.5x or doubler
voltage conversion mode). It is described by the following:
PDISS =
1
h –1 VO × IO (Efficiency η mainly depends on VI and also on IO. See efficiency graphs.)
PDISS must be less than that allowed by the package rating. See the absolute maximum ratings for 20-pin PWP
package power-dissipation limits and deratings.
