LT1613CS5#PBF

LINEAR TECHNOLOGY  LT1613CS5#PBF  直流-直流开关升压, 稳压器, 可调, 1.1V-10V输入, 1.23V-34V输出, 300mA输出, SOT-23-5

The is a current-mode DC-to-DC Converter intended for small and low power applications. It operates from an input voltage as low as 1.1V and switches at 1.4MHz, allowing the use of tiny, capacitors and inductors 2mm or less in height. Its small size and high switching frequency enables the complete DC/DC converter function to take up less than 0.2 square inches of PC board area. Multiple output power supplies can now use a separate regulator for each output voltage, replacing cumbersome quasi-regulated approaches using a single regulator and a custom transformer. A constant frequency, internally compensated current-mode PWM architecture results in low, predictable output noise that is easy to filter. The high voltage switch on the LT1613 is rated at 36V, making the device ideal for boost converters up to 34V as well as for single-ended primary inductance converter SEPIC and flyback designs.
