EL7640 Description

The boost converter in the EL7640, EL7641, and EL7642 is a current mode PWM type integrating an 18V N-channel MOSFET. Operating at 1.2MHz, this boost can operate in either P-mode for superior transient response, or in PI-mode for tighter output regulation. Using external low-cost transistors, the LDO controllers provide tight regulation for VON, VOFF, as well as providing start-up sequence control and fault...
