The LTC939CS#PBF is a DC-DC Switching Voltage Regulator manufactured by Linear Technology Corporation that can deliver efficient and cost effective power conversion. It is a synchronous buck regulator designed for use with an external MOSFET. The regulator supports switching up to 1A and provides output voltage regulation with a ±2mV minimum for a load range of 1-500mA. It integrates protection features, including short-circuit protection and over-current protection. The LTC939CS#PBF is suitable for a variety of applications, including automotive, consumer electronics, medical, and communications applications.

The LTC939CS#PBF supports a wide range of output voltages and currents. It can provide 3V to 36V output at up to 500mA with ±2% accuracy over the entire load range. The regulated output voltage is factory pre-set, allowing the user to configure the device without an external resistor. It can also be used with very low input voltage, down to 1.8V. This capability makes it well suited for battery-driven applications.

The LTC939CS#PBF includes various features that make it ideal for use across a range of applications. It includes a configurable soft-start function to minimize current surge at start-up. It also has advanced protection features, including short-circuit protection, load regulation, and over- current detection which can be used to prevent damage to the device. Additionally, the LTC939CS#PBF features excellent thermal performance, with an exposed die pad for improved heat dissipation and an operating temperature range of -40°C to +125°C.

The LTC939CS#PBF is a synchronous buck regulator that works by controlling the output voltage of a power supply. It uses a pulse-width modulated (PWM) signal to regulate the output voltage, which is then converted to a fixed-voltage output with a synchronous buck converter. The PWM signal is generated by a built-in oscillator, and can be adjusted to control the output voltage and current. The oscillator frequency is set to eliminate the need for an external frequency-setting resistor.

The LTC939CS#PBF is designed to deliver efficient, cost effective power conversion. It integrates protection and control logic to ensure the highest level of performance and reliability. Additionally, the device offers a wide range of output voltage and current, advanced protection features, and excellent thermal performance. This makes it an ideal choice for use in automotive, consumer electronics, medical, and communication applications.
