LTC3789 – High Efficiency, Synchronous, 4-Switch Buck ...
www.analog.comThe LTC®3789 is a high performance buck-boost switch-ing regulator controller that operates from input volt-ages above, below or equal to the output voltage. The constant-frequency, current mode architecture allows a phase-lockable frequency of up to 600kHz, while an output current feedback loop provides support for battery charging.

www.ti.comThe shape of the current flowing in the inductor is similar to Figure 6. Figure 6. Buck Regulator Inductor Current As explained, the current through the inductor ramps up when the switch is on, and ramps down when the switch is off. The DC load current from the regulated output is the average value of the inductor current.

After attending a scientific symposium in 1971, he came back determined to explore this new form of chromatography. Controlling the pressure of the mobile phase was the primary control variable, and pressure programming
