Renesas Electronics Corporation PMIC - Voltage Regulators - DC DC Switching Regulators P9122-00NBGI

The P9122-00NBGI is a dual-channel synchronous step-down switching regulator from Quarktwin Technology Ltd., designed to efficiently convert input voltages ranging from 2.7V to 5.5V. It features two integrated converters, with Buck1 capable of delivering up to 2A and Buck2 up to 3A, and supports factory programmable output voltages between 0.8V and 3.4V. The device operates with a switching frequency of 2MHz and can function in either automatic PFM/PWM or forced PWM modes. This regulator is suitable for various low-power applications, including solid-state disk drive power management, low-power USB applications, set-top box power supplies, and portable gaming devices. It includes features such as power good and power on reset outputs, as well as an optional programmable sequence mode. The operating temperature range is specified from -40¬8C to +85¬8C, and the product is housed in a compact QFN 24-lead package measuring 4mm x 4mm x 0.8mm.
