PMIC - Voltage Regulators - DC DC Switching Regulators

The LTC3112EFEPBF is a synchronous step-down switching regulator with a wide input voltage range, low output ripple and fast transient response time. It is a high-performance regulator that can provide up to 6A (2.5A/3A) continuous output current over a wide input voltage of 5V to 48V. The device integrates input power-on detect, soft-start, over-temperature protection and sub-20mV output ripple. This DC-DC converter also features integrated power switch, built-in loop compensation, and internal soft-start, thus allowing for an easy implementation of a wide range of regulator applications.The device is ideal for high current and low noise applications such as industrial systems, telecommunications, automotive, and other complex power-supply requirements. The LTC3112EFEPBF is designed to minimize board area, making it suitable for applications with limited space. Additionally, the integrated loop compensation and soft-start features improve the system stability, while reducing components counts and complexity of the power supply design. The LTC3112EFEPBF is a synchronous buck regulator with a wide 4.75V to 45V input voltage range, a single resistor controlled programmable output voltage down to 0.600V and a power switch of 600mA/3.3A. The device includes a 3A integrated MOSFET, thermal protection, and current limit circuits for output over-current and over-temperature protection.The device supports current-mode control, pulse-skipping, a wide operating frequency up to 5MHz, and a peak current limit up to 150%. Additionally, the LTC3112EFEPBF provides a selection switch for Pulse-Skip Mode/Burst ModeEnable and OCPpre-bias, low output dropout voltage, fast transient response time and fast transient load of up to 6A.The LTC3112EFEPBF also features an adjustable output voltage ramp and a synchronous-rectifier enable/reset pin. The integrated soft start reduces the inrush current and ensures smooth start-up of the regulator. Additionally, the device implements a 0.1uA shutdown quiescent current.The LTC3112EFEPBF is an efficient, cost-effective synchronous step-down switching regulator with wide input voltage range and low output ripple. The device provides efficient power conversion, fast transient response time, built-in current limit and thermal protection. The device is an ideal choice for high current and low noise industrial applications such as telecommunications, automotive, and other complex power-supply applications.
