The LT1952MPGN-1#PBF Voltage Regulator is part of Linear Technology’s DC/DC switching controller family and is widely used in various applications. It provides pinned voltage regulators and simple, low power step-down DC/DC conversion for battery-operated products. The LT1952MPGN-1#PBF is a monolithic, low noise, high efficiency DC/DC converter. The parts offer true zero-load quiescent current, excellent noise immunity, and undershoot protection. It is also very efficient over a wide load range, allowing it to be used in a wide variety of low power and portable applications. The LT1952MPGN-1#PBF is a monolithic step-down regulator that operates from a wide input voltage range of 2.7V to 28V. The device is capable of delivering up to 2A of continuous output current in a wide range of temperatures and is capable of regulating outputs down to 0.6V. The device is designed for use in applications that require low noise and low power dissipation.The LT1952MPGN-1#PBF is designed to provide a regulation voltage from most low voltage power supplies with a current limit of 200 mA. The output is adjustable and can be programmed for a wide range of voltages. The LT1952MPGN-1#PBF has both continuous and discontinuous latching modes with programmable regulation thresholds. For discontinuous latching modes, the regulation threshold can be programmed up to 1.14V.The device also has a range of programmable features, including frequency limit control, proportional gain control, and a slew rate limit control. The LT1952MPGN-1#PBF also includes a proprietary soft-start circuit to provide controlled output voltage ramp up during start-up and to reduce inrush current during start-up.The LT1952MPGN-1#PBF is optimized for low power and incorporates a proprietary PowerSave mode that automatically reduces the output voltage to maintain optimal battery life without sacrificing system performance. This reduces the power dissipation of the part by reducing the quiescent current. The device includes a low noise gate driver and an under-voltage lockout feature that reduces gate voltage below the threshold when the input voltage is below a pre-set threshold.The LT1952MPGN-1#PBF is an ideal choice for applications that require low noise, high efficiency and reliable performance. The device is well suited for use in applications such as laptop computers, cellular phones, and other portable consumer electronics. The monolithic construction and onboard components make the part easy to design into a printed circuit board. The LT1952MPGN-1#PBF provides reliable performance in the selected application and reduces board space while maximizing efficiency.
