A DC-to-DC step-down switching regulator is an electronic circuit that converts a higher voltage DC input to a lower voltage DC output. It does this by switching the input voltage on and off at a high frequency, and then filtering and smoothing the resulting waveform to produce the desired output voltage. This type of regulator is used in a wide range of applications, including power supplies, battery chargers, and voltage regulators for electronic circuits.

The ATDC1934 is such a high-efficiency, high-frequency, and wide input range DC-to-DC step-down switching regulator. It provides up to 0.7A of output current, with a fixed switching frequency of 660kHz. This current-mode PWM controlled converter employs a proprietary control scheme that switches the device into a power-saving mode during light load, thereby extending the range of high-efficiency operation.
