TPS61170DRVT

Step-Up Boost DC/DC Converters Integrated Switch, Texas Instruments### 直流/直流开关调节器转换器（集成开关），Texas InstrumentsTexas Instruments 的此系列高度集成的高效开关稳压器包括步升（升压）、步降（降压）、步升/降（增压/降压）和反相类型，为每个直流稳压器应用提供高效的解决方案。

The is a High Voltage Boost Converter that can be configured in several standard switching-regulator topologies, including boost and SEPIC. The device has a wide input-voltage range to support applications with input voltage from multicell batteries or regulated 5, 12V power rails. It operates at a 1.2MHz switching frequency, allowing the use of low-profile inductors and low-value ceramic input and output capacitors. External loop compensation components give the user flexibility to optimize loop compensation and transient response. The device has built-in protection features, pulse-by-pulse over-current limit, soft start and thermal shutdown. The FB pin regulates to a reference voltage of 1.229V. The reference voltage can be lowered using a 1-wire digital interface EasyScale™ protocol through the CTRL pin. Alternatively, a pulse width-modulation signal can be applied to the CTRL pin. The duty cycle of the signal reduces the feedback reference voltage proportionall
