LM5165/LM5165-Q1 Synchronous Buck Converters

Texas Instruments LM5165/LM5165-Q1 Synchronous Buck Converters are compact, easy-to-use, 3V to 65V ultra-low IQ synchronous buck converters with high efficiency over wide input voltage and load current ranges. With integrated high-side and low-side power MOSFETs, up to 150mA of output current can be delivered at fixed output voltages of 3.3V, 5V, or an adjustable output. The Texas Instruments LM5165/LM5165-Q1 converters are designed to simplify implementation while providing options to optimize the performance of the target application. Pulse Frequency Modulation (PFM) mode is selected for optimal light-load efficiency or Constant On-Time (COT) control for nearly constant operating frequency. Both control schemes do not require loop compensation, providing excellent line and load transient response and short PWM on time for large step-down conversion ratios. The LM5165-Q1 devices are AEC-Q100 qualified for automotive applications.
