Texas Instruments SN6505BDBVR
Low-noise, 1-A, 420-kHz transformer driver with soft start for isolated power supplies
Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 3.2-3.4 V |
| Output 1 | 5 V / 0.1 A |
Description
TMDSCNCD280039C is a low-cost evaluation and development board for TI C2000™ MCU series of F28003x devices. It comes with a HSEC180 (180-pin high-speed edge connector) and, as a controlCARD, is ideal for initial evaluation and prototyping. For evaluation of TMDSCNCD280039C, a 180-pin docking station TMDSHSECDOCK is required and can be purchased separately.
Features
- Push-pull driver for transformers
- Wide input voltage range: 2.25 V to 5.5 V
- High output drive: 1 A at 5 V supply
- Low RON 0.25 Ω max at 4.5 V supply
- Ultra-low EMI
- Spread spectrum clocking
- Precision internal oscillator options: 160 kHz (SN6505A) and 420 kHz (SN6505B)
- Synchronization of multiple devices with external clock input
- Slew-rate control
- 1.7 A Current-limit
- Low shutdown current: <1 μA
- Thermal shutdown
- Wide temperature range: –55°C to 125°C
- Small 6-Pin SOT23 (DBV) package
- Soft-start to reduce In-rush current
Typical applications
- Isolated power supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, low-power LAN, Low-noise isolated USB supplies, Process control, Telecom supplies, Radio supplies, Distributed supplies
- Medical instruments
