产品描述

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 line and load regulation and simple frequency compensation over the device's 2.2V to 12V input voltage range. The LM2698 sets the standard in power density and is capable of supplying 12V at 400mA from a 5V input. The LM2698 can also be used in flyback or SEPIC topologies.

The LM2698 SIMPLE SWITCHER 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 frequency compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. Switchers Made Simple® software is available to ensure a quick, easy and assured design. The LM2698 is available in a low profile 8-lead VSSOP (DGK) package.
