The KTB8316 is a precision adaptive-on-time (AOT) step-down (buck) switching regulator. The device has class-leading accuracy, fast transient response and high efficiency. Additional features include current, over/under voltage and thermal protections.
The AOT control along with a thermally enhanced PwrCSP™ package provides a best-in-class solution with reduced size external components for mobile and non-mobile applications. The step-down buck regulator operates over a user set 0.3V to 3.3V output range. Please review the Part Number Options Table to determine the output range for each product option.
Switching frequency options of 1MHz, 2MHz and 4MHz are available with Forced-PWM or Auto-skip mode at light loads.
The KTB8316 is available in RoHS and Green compliant PwrCSP™ HP-WLCSP-6 Package.
