DC DC Converters

The PI01S1215A DC DC converter is a family of high- density, isolated, point-of-load (POL) converters, which provide 15 W of output power when operated in natural convection. This converter is designed for direct connection to a battery or an unregulated bus power in a variety of applications such as food-service equipment, vending machines, gaming and amusement machines, portable electronic equipment and industrial and telecom equipment.The PI01S1215A is a wide input voltage range DC-DC converter and features a full load efficiency of up to 95% for low power applications. Its design allows for a wide input voltage range (5.5 ~ 32 Vdc) and it operates on regulated or unregulated voltages in input conditions. The device provides a 12V regulated output and up to 1.5A continuous output current. The PI01S1215A power module can operate in either continuous current or constant voltage modes, making it well-suited to today\'s demanding battery operated portable systems.The device offers adjustable output voltage, constant current mode, integrated thermal and current protection, and wide temperature range operation (-40°C to +85°C). A unique feature of this device is its integrated 0.01Ω MOSFET driver, which allows working at higher input and output voltages and more efficient operation than conventional drivers.The PI01S1215A is also designed with a high MTBF (Mean Time Between Failures), enabling it to provide several years of reliable operation under typical operating conditions. Additionally, it incorporates active voltage clipping on the input and output pins which helps protect against an over-voltage on the power pins.The working principle of the PI01S1215A is based on a boost conversion topology. The device operates by switching between two operating states, at a high and low frequency. In the first state, the converter is in the boost mode, boosting the input voltage up to slightly higher than the output voltage. The second state is in the flyback mode, where the input voltage is reduced and the inductor is used to store the energy. Once the output voltage reaches the setpoint, the converter switches back into boost mode.The PI01S1215A also uses synchronous rectification for better efficiency. In synchronous rectification, the main switching transistor is replaced by a low on-resistance metal oxide semiconductor field- effect transistor (MOSFET), which helps in reducing the switching losses by conducting only when the output voltage is below the setpoint value. Additionally, the MOSFET helps to reduce the input ripple currents, providing better regulation performance even in light-load conditions. Overall, the PI01S1215A is an excellent choice for a variety of industrial, portable, and telecom applications which require a DC-DC converter with high power density and customizable output voltage. The device offers a high-performance power solution with long-term reliability and flexibility for a wide range of operating conditions.
