Features

* Current mode boost regulator - Fast transient response - 1% accurate output voltage - 18V/3A integrated FET - >90% efficiency
* 2.6V to 5.5V VIN supply
* 2 LDO controllers for VON and VOFF - 2% output regulation - VON-slice circuit
* High speed amplifiers - 150mA sh

Applications

* The boost converter in the EL7640A, EL7641A, and EL7642A is a current mode PWM type integrating an 18V NHchannel 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, th
