Isolated Offline Regulator

Isolated Offline Regulator Linear Technology Corporation announces the LT3798, an isolated flyback controller with single stage active power factor correction (PFC). A power factor of greater than 0.97 is accomplished by actively modulating the input current, eliminating the need for an extra switching power stage and associated components. In addition, no opto-isolator or signal transformer […]

Smart 24V Step-Down Regulator

Smart 24V Step-Down Regulator Linear Technology Corporation introduces the LTC3613, a high frequency controlled on-time synchronous step-down DC/DC converter with differential output voltage sensing and clock synchronization. The controlled on-time, valley current mode architecture enables a very fast transient response by increasing its operating frequency during a transient event, allowing the LTC3613 to recover from […]
