RT8580 - 36V DC/DC Boost Converter

Datasheet Summary

Description

The RT8580 is a high performance, low noise, DC/DC Boost Converter with an integrated 0.5A, 1Ω internal switch.

The RT8580's input voltage ranges from 3V to 5.5V, and it can support the output voltage up to 40V.

Features

  • of RT8580 include : 1) input undervoltage lockout, 2) output over-voltage protection, and 3) over-temperature protection. The soft-start function and PWM loop compensation is built-in internally to save external soft-start capacitor and PWM loop compensation components. By operating at 500kHz switching frequency, the RT8580 system board can be made compact to achieve low system BOM cost. The RT8580 is available in the tiny package type SOT-23-6. Marking Information 0E=DNN 0E= : Product Code D.

® RT8580 36V DC/DC Boost Converter General Description The RT8580 is a high performance, low noise, DC/DC Boost Converter with an integrated 0.5A, 1Ω internal switch. The RT8580's input voltage ranges from 3V to 5.5V, and it can support the output voltage up to 40V. When used in optical receiver applications requiring 80V to drive the APD (Avalanche Photo Diode), the output voltage of RT8580 can be doubled up by a typical voltage doubler circuit. The RT8580 adapts fixed frequency, current mode PWM control loop to regulate the output voltage with fast transient response and cycle-by-cycle current limit protection. The protection features of RT8580 include : 1) input undervoltage lockout, 2) output over-voltage protection, and 3) over-temperature protection.
