PMIC - Voltage Regulators - DC DC Switching RegulatorsThe LM5166DRCT is a DC-DC switching regulator designed to provide an adjustable output voltage in applications where the minimum operating voltage is greater than that of the supply voltage. This device is well-suited for powering critical subsystems in automotive, telecom, and computing platforms.The device has a wide input voltage range of 3.2 V to 40 V, and provides an adjustable output voltage range of 0.75 V to 70 V. The output voltage is adjustable using an external voltage reference. The device also offers a wide range of operating frequencies up to 1.5 MHz and a programmable current-limit protection to ensure proper system operation.The device offers excellent transient response characteristics and utilizes advanced control techniques to ensure fast and accurate voltage regulation. The regulator features a power-saving active discharge function to ensure proper operation in low-voltage systems. Additionally, the device incorporate a precision fixed oscillator, wide frequency-modulation range, and switch-current protection to ensure high reliability and system stability.This device achieves high level of efficiency and very low switching losses due to its synchronous rectification and lower operating temperature. The device\'s integrated high-side MOSFET and low-side MOSFET provides improved power-stage efficiency compared to a non-integrated solution, which helps to reduce system cost.The LM5166DRCT includes a unique thermal-protection circuit which monitors the die temperature and reduces the switch duty cycle when the die temperature exceeds a specific temperature threshold. This protection circuit prevents the device from overheating under heavy load conditions.All the features ensure that the LM5166DRCT is an ideal device for a wide range of automotive, consumer, and industrial DC-DC switching regulator applications. The device is fully tested and approved by major automotive-electrical standard organizations and is offered in packages ranging from 2.8 x 2.8 mm up to 14.3 x 14.3 mm. The device is available with a range of package types, including surface-mount, thru-hole, and Chip-on-Board (COB) options.
