TD1464  _{1.5A 150KHz PWM Buck DC/DC Converter}

(DATASHEET)

TD1464 is a monolithic asynchronous buck regulator. The device provides 1.5A of continuous load current over a wide input voltage of 9V to 40V. It uses current mode control to regulator the output voltage and provides fast transient response. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. Anti-ring function is to reduce the influence of EMI. This device, available in a SOP-8 package, provides a very compact system solution with minimal reliance on external components..
