The LTC1966IMS8#PBF is a high-speed, general-purpose, synchronous buck-boost converter optimized for low-voltage, high-current applications. The device features a wide range of operating frequencies, high-efficiency power conversion, and typically low output ripple. The LTC1966IMS8#PBF is a precision-molded, medium-density power conversion solution.

The LTC1966IMS8#PBF is a high-efficiency, single-phase, RMS-to-DC converter optimized for use in low-voltage, medium-current applications. The device offers excellent performance in a tiny, low-profile surface-mount package. The device is capable of outputting 4A of continuous current and up to 6A of peak current. The device features ultralow output ripple and precise voltage regulation from 0.5V to 3.6V while providing higher-than-normal efficiency. The operating frequency can be adjusted between 200kHz and 1.2MHz via an external switching frequency control.

The LTC1966IMS8#PBF is an ideal solution for high-current applications such as portable electronics, consumer and industrial motor drives, battery chargers, and point-of-load converters. The device has the capability to generate a clean, adjustable DC output voltage from a wide range of input voltages within a single-phase system. The highly competitive efficiency of LTC1966IMS8#PBF power converter provides a power saving advantage in battery-operated applications.

The LTC1966IMS8#PBF is based on a synchronous buck-boost topology and offers a wide range of input-to-output voltage conversion. When the input voltage is higher than the output, the device operates as a buck converter, and the switch turns on, allowing the input current to flow through the inductor, giving rise to an increasing inductor current. When the inductor current reaches its peak, the switch turns off and the stored inductor current flow through the diode and into the output capacitor, resulting in a decrease in output voltage. In the buck-boost mode, the device operates similarly, except that the inductor current decreases during the switch on-time and increases during the switch off-time, resulting in a net transfer of energy from the input to the output.

The device offers precision voltage regulation and adjustable operating frequency in a small, easy-to-use package. The internal current-mode control loop ensures fast transient response and excellent line regulation. The enable input can be used to put the device into low-power standby mode, thereby reducing power consumption. The user adjustable soft-start feature eliminates inrush currents due to the large input-output voltage differential and enables longer output connection cables.

In summary, the LTC1966IMS8#PBF is a high-performance, robust and energy-efficient RMS-to-DC converter designed for low-voltage, high-current, single-phase applications. Its wide input and output voltage range, wide operating frequency, adjustable soft-start and enable inputs, and high efficiency make it a great choice for powering portable electronics, motor drives, battery chargers, and point-of-load converters.
