LT1172IS8#PBF, Высокоэффективный импульсный регулятор напряжения с внутренним силовым ключом 5А

Step-Up (Boost) Regulators, Internal Power Switch Boost, Linear Technology
Linear Technology presents step-up (boost) switching regulators with both synchronous and non-synchronous internal switches. The high efficient DC-DC converters have a wide range of input voltages and switching frequencies. Some products feature unique properties that can help increase battery run time in handheld devices or even be managed in a range of switching configurations. Typical applications would be power inverters, fully floating multiple outputs and 5V logic supplies.
