LM2698MM-ADJ/NOPB

Импульсный повышающий DC-DC стабилизатор, регулируемый, 2.2В-12В (Vin), 2.2В-17В, 1.9А, VSSOP-8.

The LM2698MM-ADJ/NOPB is a SIMPLE SWITCHER® general purpose PWM Boost Converter for use with DSL modems. The 1.9A/18V/0.2R internal switch enables the LM2698 to provide efficient power conversion to output ranging from 2.2 to 17V. It can operate with input voltage 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 2.2 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.
