TPS61170 采用了 2x2mm QFN 封装的 1.2A 开关、高压升压转换器
TPS61170 描述
The TPS61170 is a monolithic high voltage switching regulator with integrated 1.2-A, 40-V power MOSFET. It 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 multi-cell batteries or regulated 5-V, 12-V power rails.
The TPS61170 uses a 1.2-MHz switching frequency, allowing the use low-profile inductors and low-value ceramic input and output capacitors. The external loop compensation gives the user flexibility to optimize loop compensation and transient response. The device has built-in protection features, such as pulse-by-pulse overcurrent limit, soft start and thermal shutdown.
The feedback reference voltage of the FB pin is 1.
