Nisshinbo Micro Devices Inc. Voltage Regulators - DC DC Switching Regulators RP500L331A-TR

The RP500L331A-TR is a step-down DC/DC converter from Quarktwin Technology Ltd., designed to provide a fixed output voltage of 3.3V with a maximum output current of 600mA. This device operates within an input voltage range of 2.55V to 5.50V and features a high efficiency synchronous rectifier. The output voltage accuracy is ¬±1.5% for voltages equal to or greater than 1.6V, and ¬±24mV for lower voltages. The RP500L331A-TR includes built-in protection circuits such as a current limit circuit and a latch-type protection circuit for over-current conditions. It supports two switching modes: automatic PWM/VFM mode change and fixed PWM mode, allowing for flexibility in various applications. The device has a typical supply current of 400OºA in PWM mode and a standby current of a maximum of 5OºA. This regulator is packaged in a compact DFN1616-6 format, facilitating high-density mounting on circuit boards. It is suitable for applications including power sources for battery-powered devices, handheld communication equipment, and portable electronics.
