Nisshinbo Micro Devices Inc. Voltage Regulators - DC DC Switching Regulators RN5RK332A-TR-FE

The RN5RK332A-TR-FE is a CMOS-based VFM step-up DC/DC converter IC designed for applications requiring a boost in voltage. It operates with a low supply current and offers high output voltage accuracy, making it suitable for battery-powered devices. The output voltage can be set between 2.0V and 5.5V in 0.1V increments, with a typical output voltage accuracy of ±2.5%. This regulator features a low ripple and noise operation, with a typical efficiency of 85% at a 2V input and 10mA output. The device includes a chip enable function that minimizes standby current to approximately 0µA. The RN5RK332A-TR-FE is packaged in a compact SOT-23-5 format, allowing for high-density mounting on PCBs. It requires only three external components: an inductor, a diode, and a capacitor, simplifying the design process. Applications include powering cameras, camcorders, and other handheld communication devices that require a higher voltage than the battery supply.
