TP3605概述
The TP3605 is high efficiency Boost DC/DC Converter, fixed frequency, current-mode step-up converter with output to input disconnect. A PWM step-up DC/DC converters optimized to provide a high efficiency solution to medium power system. Its PWM circuitry with built-in 2.1A@200mΩ power mosfet makes this converter highly power efficiently. Selectable high switching frequency allows faster loop response and easy filtering with a low noise output. The non-inverting input its error amplifier is connected to an internal 0.6V precision reference voltage. Soft-start time can be programmed with an external capacitor, which sets the input current ramp rate. Current mode control and external compensation
network make it easy and flexible to stabilize the system. the devices or a single-cell Li-ion Battery with a 1MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
