XL1509-ADJE1 Adjustable voltage reducer IC 1.2 to 37 V 5 pcs

The XL1509 IC is a DC-DC step-down converter with a fixed operating frequency of 150 kHz and is capable of 2 A output current with high efficiency, low ripple, and line and load regulation.

This IC is available in different versions and its serial number changes depending on the output voltage, for example, the XL1509-5 has a fixed 5 V output and versions of 3.3 V, 12 V and adjustable output.

This IC is a buck IC type XL1509-ADJE1, the output is adjustable from 1.23 to 37 V.

The PWM output of this module can be changed from 0 to 100 percent and has a current protection circuit. When the current limiting function occurs, the frequency drops from 150 kHz to 50 kHz and does not require external compensating elements.
