Analog Devices LT8350S | Demoboard EVAL-LT8350S-AZ
LT8350S 40VIN, 18VOUT, 6A Synchronous Buck-Boost Silent Switcher 2
Overview
| Topology | Buck-Boost Converter |
| Input voltage | 3-40 V |
| Output 1 | 12 V / 2.5 A |
Description
The EVAL-LT8350S-AZ Evaluation board is a 40V synchronous buck-boost converter featuring the LT®8350S. It drives up to 2.5A load at 12V output when VIN is between 9V and 40V and will run down to 3VIN with reduced output current. EVAL-LT8350S-AZ runs at 350kHz switching frequency with spread spectrum frequency modulation (SSFM) disabled. When enabled, SSFM spreads the switching frequency of the LT8350S from fSW to fSW + 25% for a reduced electromagnetic interference (EMI) emission.
Features
- 3V–40V Operating Input Voltage
- Reduced EMI emissions for CISPR 25 Class 5
- Spread Spectrum Frequency Modulation
- Input and Output EMI filter
- In-built Input and Output high-frequency capacitors
- Adjustable UVLO, VOUT, fSW, Output Current andLimit
- Voltage-Monitoring (PGOOD) and Current-Monitoring(ISMON)
- Configurable SYNC pin for Forced Continuous Mode(FCM), Discontinuous Conduction Mode (DCM),SSFM, and external Frequency Synchronization
- Feed Forward Function for improved transient response
Typical applications
