摘要： There is described a device for converting an input signal having a given input voltage (Vbat) value (Vbat) into an output signal having an output voltage (Vout) (Vout) different from the input voltage (Vbat). The device comprises a main module (56), arranged between an input terminal (54) and a first circuit node (N1 ), The device is adapted to output at the first circuit node (N1 ) a pulse-width- modulated (PWM) signal switching between a first voltage value and a second voltage value, defining a switching range (SR(i)), by switching successively between a first mode of operation and a second mode of operation. The switching range (SR(i)) of the pulse width modulation (PWM) has an amplitude, calculated as the absolute difference between the first and the second voltage value, inferior or equal to half the input voltage (Vbat).
摘要翻译：描述了用于将具有给定输入电压（Vbat）值（Vbat）的输入信号转换为具有与输入电压（Vbat）不同的输出电压（Vout）（Vout）的输出信号的装置。该装置包括布置在输入端子（54）和第一电路节点（N1）之间的主模块（56），该装置适于在第一电路节点（N1）处输出脉宽调制（PWM）通过在第一操作模式和第二操作模式之间连续切换，在第一电压值和第二电压值之间进行信号切换，限定切换范围（SR（i））。脉宽调制（PWM）的切换范围（SR（i））具有作为第一电压值和第二电压值之间的绝对差计算的振幅，其劣于或等于输入电压的一半（Vbat）。
