PURPOSE:To enable such pulse width control operation as the switching duty ratio is varied while maintaining constant switching period by inserting a movable core into a core gap through a piezoelectric actuator thereby varying the inductance of resonance coil. CONSTITUTION:Control circuit 14 for a ...

A comparator circuit () provides a signal (V) when voltage (V) across the storage capacitor () falls a reference voltage, and an enable circuit () responds to the comparator signal (V) and an ON command signal to enable the power supply (). The modulator () further includes a network...
These two options will be enabled in the Control_Logic/enable_pwm subsystem shown in Fig. 25, where we have used an interesting combination of NXP Toolbox library blocks and Simulink Coder Custom Code blocks to call the FTM function that enables the trigger generation, as it is shown in Fig...

Dual 3+1 PWM Controller with Current Monitor for IMVP-7/VR12™ CPUs ISL95839 The ISL95839 Pulse Width Modulation (PWM) controller IC provides a complete solution for IMVP-7/VR12™ compliant microprocessor and graphic processor core power supplies. It provides the control and protection for ...
Done here to enable Vin faults when auxiliary power is driven via USB connected to the DP-PIM. State 2: Fault Active Stays here until all fault conditions are cleared. State 3: Standby PWM is active, and the control mode (open loop or closed loop) is saved. ...
Intuitively, a pattern specifies how many spatial directional beams a TRP uses to enable its discovery by the UEs. Figure 1 reports all the possible SSB patterns highlighting that a higher number of beams is used for high frequencies (e.g., millimeter waves). Higher values of \(N_{\text ...

The EN pin provides enable/disable functionality. The typical shutdown current is 2 µA when disabled. As soon as the EN pin is pulled up the device is enabled and the internal 1.3 ms soft-start takes place. Pulse-by-pulse current sensing on both power elements implements an effective co...
