The TPS6211x devices are a family of low-noise synchronous step-down DC-DC converters that are ideally suited for systems powered from a 2- to 4-cell Li-ion battery or from a 12-V or 15-V rail.
The TPS6211x devices are synchronous pulse width modulation (PWM) converters with integrated N- and P-channel power MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To achieve highest efficiency over a wide load-current range, the converter enters a power-saving, pulse frequency modulation (PFM) mode at light load currents. Operating frequency is typically 1 MHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 0.8 MHz to 1.4 MHz. For low-noise operation, the converter can be operated in PWM-only mode. In shutdown mode, the current consumption is reduced to less than 2 µA. The TPS6211x family of devices are available in the 16-pin (RSA) VQFN package, and operate over a free-air temperature range of 40°C to 85°C.

多个降压转换器提供的低电量输入 (LBI) 通常用于在输入电压低于设置的阈值时关闭转换器。电池在其寿命结束时应当充电或更换,这可防止对电池和信号造成损坏。具有内部电阻的电池在负载提高时会导致电压下降。在监控电池级别时,这种内部电阻会带来挑战。当转换器关闭并且电流降至零时,通过电池的内部电阻降低的电流导致电池的终端电压升高。在许多情况下,电压升高到 LBI (...)
