Texas Instruments LM5170
The LM5170 controller provides the essential high voltage and precision elements of a dual-channel bidirectional converter. It regulates the average current flowing between the high voltage and low voltage ports in the direction designated by the DIR input signal. The current regulation level is programmed through analog or digital PWM inputs.| Part No. | LM5170 |
