Allegro added a 3A buck converter which uses valley current-mode control ideal for applications requiring high switching frequencies, high input voltages (9V-46V) and low output voltages (0.8V-15V).

The A4403 is a buck converter that uses valley current-mode control. This control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

National Semiconductor's LM5116 is a 6-V to 100-V current-mode buck controller utilizing emulated current-mode technology to reduce noise sensitivity of the PWM circuit. National Semiconductor’s ...

Texas Instruments has introduced a 16V input, 40A synchronous DC/DC buck converter with internally compensated ‘advanced-current-mode’ (ACM) control supporting frequency synchronisation. Called ...

National Semiconductor has introduced its first 6V to 100V current-mode buck controller. The LM5116 is designed for step-down regulator applications from a high voltage or widely varying input supply.

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...
