Nisshinbo Micro Devices Inc. Voltage Regulators - DC DC Switching Regulators RP504L141D-TR

The RP504L141D-TR is a 600 mA PWM/VFM step-down DC/DC converter designed for efficient voltage regulation in compact applications. It operates within an input voltage range of 2.3 V to 5.5 V and provides adjustable output voltages from 0.8 V to 3.3 V in 0.1 V increments, with an output voltage accuracy of ±1.5% or ±18 mV depending on the output level. The device features a low supply current of approximately 25 µA in VFM mode and a maximum standby current of 5 µA, making it suitable for battery-powered devices. The RP504L141D-TR employs synchronous rectification to enhance efficiency by using built-in switching transistors instead of diodes, which also reduces the overall component count. It supports two power control methods: forced PWM control for noise reduction at low output currents and PWM/VFM auto switching for improved efficiency. Protection features include overcurrent protection and a latch-type protection circuit to safeguard against prolonged overcurrent conditions. This product is available in multiple package options, including DFN(PL)1216-6F, DFN1616-6B, and SOT-23-5, allowing for flexibility in design and layout. It is suitable for applications such as handheld communication devices, cameras, and other portable equipment where space is limited and efficiency is critical.
