TD1464 1.5A 150KHz PWM Buck DC/DC Converter

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 .
