LM2698 Datasheet (National Semiconductor) - SIMPLE SWITCHER 1.35A Boost Regulator

LM2698, SIMPLE SWITCHER 1.35A Boost Regulator

The LM2698 is a general purpose PWM boost converter.

The 1.9A, 18V, 0.2ohm internal switch enables the LM2698 to provide efficient power conversion to outputs ranging from 2.2V to 17V.

It can operate with input voltages as low as 2.2V and as high as 12V.

Current-mode architecture provides superior l

LM2698 Features

* a pin selectable switching frequency of either 600kHz or 1.25MHz. This promotes flexibility in component selection and filtering techniques. A shutdown pin is available to suspend the device and decrease the quiescent current to 5µA. An external compensation pin gives the user flexibility in setting
