T1, T2: MJD47 (Digikey: 497-2482-1-ND) Note 1: I realize that the zeners cannot dissipate enough power. Sometimes I place zeners in parallel, each of them in series with a 50Ω resistor. Those series resistors make sure that the current distributes itself somewhat evenly over the ze...
The main difference is that the NFET is replaced with a voltage regulator. the voltage regulator steps-down the input voltage much like the NFET did, but it is designed so that its output voltage is set by the ratio between two resistors (R2+R4, and R1). The current-limit circuit works...

The constant on-time PWM control scheme operates without sense resistors and provides 100ns response to load transient response while maintaining nearly constant switching frequency. To eliminate noise in audio applications, an ultrasonic mode is included, which maintains the switching frequency above ...

A constant on-time PWM control scheme operates without sense resistors and provides 100ns response to load transients while maintaining a relatively constant switching frequency. The unique ultrasonic mode maintains the switching frequency above 25kHz, which eliminates noise in audio applications. Ot...
connecting leads to the resistors. I have verified this is the correct voltage reading by using different methods and oscilloscopes. I have two theory: there is some going on in the PCB that is causing this OR the resistance of the current sense resistors is dropping during ...
Hello. I'm using two 150mOhm current sense resistors in series to measure low side current of an H-Bridge. During normal operation my current is below 1A (voltage on the high side > 150V). During inrush events currents can be as high as 15A. I'm seeing something st...
