The device operates over a wide input voltage range to support a variety of applications with input voltage from regulated 5V and 12V power rails and multicell batteries.<\/p>\n<p>KTB8370 employs Kinetics\u2019 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 KTB8370 easy to use.<\/p>\n<p>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 over-voltage protection, and thermal shutdown.<\/p>\n<p>KTB8370 are available in RoHS and Green compliant 20-bump 1.7mm x 2.0mm x 0.6mm wafer-level chipscale WLCSP20
