1，TPS54160 4060V输入15V输出1A电感量150uH1A电感鸣响

电感鸣响一般是振荡频率过低所致，你可以调整电路的振荡频率，使之超过30kHz即可！！答题不易，如有帮助请采纳，谢谢！！

2，负一伏电压产生电路

用电荷泵器件TPS60400或TPS60401，可以从+5V得到-5V，因此你可以用TPS60400先从+5V转换出一路-5V电压，然后在-5V和MCP6004的负电源脚之间接一支一支4V的齐纳稳压二极管，这样一来MCP6004就得到-1V电压。TPS60400或TPS60401的外围电路也很简单，只要3支1μF的小电容即可。TPS60400的实用电路如下图——

3，TPS40210芯片BP脚的功能是什么接了一个电容对地电容坏了电压就没有了

网上很方便查，5 Pin Configuration and FunctionsDGQ10-PinTop ViewDRC10-PinTop ViewPin FunctionsPINI/ODESCRIPTIONNAMENO.BP 9 O Regulator output pin. Connect a 1.0 μF bypass capacitor from this pin to GND. 稳压器输出引脚。在此引脚与GND之间连接一个1.0μF旁路电容。BP就是旁路（ByPass）的意思。一般是自举电容之类的。由于芯片内部制造电容电感很困难（制造半导体器件如晶体管却很容易），所以设计时把集成电路中需要接电容的地方用引脚引出来，在芯片外面接。所以越大的芯片引脚越多，四周放的电容也越多。COMP 4 O Error amplifier output. Connect control loop compensation network between COMP pin and FB pin. DIS/EN 3 I Disable pin. Pulling this pin high, places the part into a shutdown mode. Shutdown mode is characterized by a very low quiescent current. While in shutdown mode, the functionality of all blocks is disabled and the BP regulator is shut down. This pin has an internal 1 MΩ pull-down resistor to GND. Leaving this pin unconnected enables the device. FB 5 I Error amplifier inverting input. Connect a voltage divider from the output to this pin to set output voltage. Compensation network is connected between this pin and COMP. GDRV 8 O Connect the gate of the power N channel MOSFET to this pin. GND 6 - Device ground. ISNS 7 I Current sense pin. Connect an external current sensing resistor between this pin and GND. The voltage on this pin is used to provide current feedback in the control loop and detect an overcurrent condition. An overcurrent condition is declared when ISNS pin voltage exceeds the overcurrent threshold voltage, 150 mV typical. RC 1 I Switching frequency setting pin. Connect a resistor from RC pin to VDD of the IC power supply and a capacitor from RC to GND. SS 2 I Soft-start time programming pin. Connect capacitor from SS pin to GND to program converter soft-start time. This pin also functions as a timeout timer when the power supply is in an overcurrent condition. VDD 10 I System input voltage. Connect a local bypass capacitor from this pin to GND. Depending on the amount of required slope compensation, this pin can be connected to the converter output. See Application Informationsection for additional details.
