PMIC - Voltage Regulators - DC DC Switching Regulators

The 88SR112HD is a high-performance DC/DC switching regulator that delivers high power conversion, ultra-low quiescent current, and fast transient response. This integrated dual-cell buck converter efficiently regulates input voltage over a wide input range and provides adjustable output voltage from 0.8V to 5.5V.The 88SR112HD offers excellent efficiency, high operating temperature withstand, and superior performance in pitch range, transient response, and power conversion. It is the perfect choice for applications that require a high-efficiency, low-cost solution. Its low quiescent current, combined with its small package size and wide operating temperature range, make it an efficient and reliable choice for many applications.The 88SR112HD is a synchronous step down switching regulator that can deliver up to 5A of continuous output current. It also features a wide input voltage range of 3.2V to 40V, making it suitable for a variety of input sources. Additionally, the 88SR112HD has built-in short circuit, overload, over temperature, and undervoltage protection.The 88SR112HD uses pulse frequency modulation (PFM) to precisely regulate the output voltage and reduce total power consumption. It is equipped with cycle-by-cycle current limit and built-in over-temperature protection for reliable operation even during extreme thermal conditions.The 88SR112HD is a very versatile device that can be used in a variety of applications. It is suitable for low-voltage power supplies and voltage regulation in industrial applications, automotive electronics, and consumer products such as tablets, cellular phones, and portable audio players.It is also compatible with a variety of control schemes, and can be used in both open loop and closed loop applications. In an open loop application, the output voltage is fixed and the duty cycle of the pulse width modulation is adjusted to achieve a gas constant or fixed voltage regulation. In a closed loop application, an external voltage reference, or an on-board error amplifier, is used to adjust the duty cycle of the pulse width modulation to regulate the output voltage. This allows for precise dynamic regulation for continuously varying loads or transient voltages.The 88SR112HD is also able to operate in multiple modes, so it can be tailored to fit a variety of applications. It offers Burst Mode operation, which reduces switching losses and reduces the device’s quiescent current during light load conditions for increased efficiency. It can also be operated in Power Save Mode to reduce the input current when the output voltage is stable and the output current is below 4A.The 88SR112HD is available in a multi-channel SOP-8 package, which enables it to be easily designed into a variety of high-current applications. Its low quiescent current, wide operating temperature range, and fast transient response make it a great choice for powering even the most demanding applications.
