PMIC - Voltage Regulators - Special Purpose

A8291SETTR-T is an advanced high-efficiency switch mode voltage regulator. It is a step-down power management integrated circuit (PMIC) that delivers a high power density and high efficiency with a wide input voltage range, low intrinsic EMI/RFI shielding noise and accurate output voltage regulation. This voltage regulator is designed for applications that require a wide input voltage range and high efficiency. It is a single-stage, non-synchronous, current mode buck regulator. This PMIC has two operating modes. In the primary mode, it is a constant frequency, current-mode, low-side synchronous buck regulator. The second mode is an open-drain regulation mode to optimize quiescent current and reduce power dissipation. It is also capable of pulse-by-pulse current limiting and thermal shutdown protection.The A8291SETTR-T can provide a wide input voltage range of 4.5V to 19V, and an output current of up to 5A. It also has an adjustable output voltage range from 0.6V to 12V. It is designed for a wide range of applications, such as post-regulators for high current applications and point-of-load (POL) regulators for intermediate bus applications.In addition to its high-efficiency, low-loss regulation, the A8291SETTR-T also features an input undervoltage lockout, soft start, output overvoltage protection, absolute current limit and short-circuit protection. It also has an efficient pulse-skipping low-power mode and a patented dynamic self-lowering current limit. The A8291SETTR-T is available in a 7-pin SOT-23 Package, making it ideal for space constrained designs. Its thermal shutdown and current limit protections also make it suitable for safety-critical applications.In summary, the A8291SETTR-T is an advanced high-efficiency switch mode voltage regulator. It has a wide input voltage range, low intrinsic EMI/RFI shielding noise, precise output voltage regulation and two operating modes. Its superior protection features, small size and high efficiency make it an ideal choice for post-regulators for high current applications and point-of-load (POL) regulators for intermediate bus applications.
