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 under-
voltage 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.

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may
affect device reliability.
Note 2. θJA is measured at TA = 25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
