Embodiment Construction

[0036] Figure 1A A two-phase DC-DC converter 100 according to an embodiment of the invention is shown. refer to Figure 1A , the two-phase DC-DC converter 100 includes a pulse width modulator 102 (also simply referred to as modulator), which includes a first pulse width modulated output (PWM1 输出 ) and the second PWM output (PWM2 输出 ). PWM1 输出 and PWM2 输出 The signal output at the place can also be called PWM1 输出 Signal and PWM2 输出 signal, essentially 180° out of phase. In other words, PWM2 输出 Signal lags (or leads) PWM1 输出 The signal is essentially 180°. exist Figure 1A Also shown in is a component failure detector 120, which is referred to below image 3 with 12 described in more detail.

[0037] The two-phase DC-DC converter 100 also includes a pair of driver-MOSFET stages 106_1 and 106_2 shown as DrMOS1 and DrMOS2. In one embodiment, each DrMOS can be used as a level shifter with low output impedance. For example, each DrMOS can be connected between a 12V rail...
