illustrate

The LM2698 PWM boost converter is a universal converter. The 1.9A, 18V, internal 0.2ohm switch allows the LM2698 to provide an output with efficient power conversion ranging from 2.2V to 17V. It can be associated with input voltages as low as 2.2V and as high as 12V. The current mode architecture provides superior line and load regulation and the 2.2V to 12V input voltage range of simple frequency compensation devices. The LM2698 has a standard setting of power density and is capable of delivering 12V from a 5V input at 400 mA. The LM2698 can also be used in flyback or SEPIC topologies.

The LM2698's SIMPLE SWITCHER ® function pin is selected as a switching frequency of 600kHz or 1.25MHz. This promotes the selection of components and flexibility in filtration technology. A shutdown pin reduces the pause device and quiescent current to 5μA. An external compensation pin allows the user to compensate at a set frequency, which makes it possible to use small, low ESR ceramic capacitor output flexibility. Switcher manufacturing simple ® software is available to ensure fast, easy, and guaranteed design. The LM2698 is a low-profile 8-lead MSOP package.
