Kinetic Technologies Unveils Synchronous Buck Regulator for IoT Applications

Kinetic Technologies, a leading innovator in electronic solutions, introduces the KTB8372, a 5A, 18V synchronous buck regulator with integrated high-side and low-side power FETs. The device operates over a wide input voltage range to support a variety of applications with input voltage from regulated 5 V and 12 V power rails and multicell batteries. The fix options for output voltage can be predefined and trimmed by the factory.

KTB8372 employs Kinetic’s proprietary advanced adaptive on-time (AOT) control for fast transient response and high output voltage accuracy. This control technique eliminates the external loop compensation network and allows the use of ceramic output capacitors without ripple-generating circuitry. These features enable a very small total solution size and make KTB8372 easy to use.

The device features an internal soft-start function to limit inrush current during start-up. The device has comprehensive built-in protection features including input voltage UVLO, high-side cycle-by-cycle peak current limit, low-side valley current limit, reverse current protection, short-circuit protection, output overvoltage protection, and thermal shutdown.

KTB8372 is available in RoHS and Green compliant 11-Pin UQFN (2.2mm x 2.5mm) package.
