My - 9892 Datasheet Top
Without proper thermal design, the warning about thermal shutdown (typically at 160°C) will trigger. Section 6: Typical Application Circuit – The Top Design Every datasheet provides a typical application circuit on the top or second page. For the my 9892, the recommended topology is:
| Part | Max VIN | Max IOUT | Efficiency | Price (1k) | |------|---------|----------|------------|------------| | My 9892 | 28V | 3A | 95% | $1.20 | | LM2596 | 40V | 3A | 80% | $2.50 | | MP2307 | 23V | 3A | 92% | $1.80 | | TPS5430 | 28V | 3A | 94% | $2.00 | my 9892 datasheet top
| Parameter | Symbol | Min | Max | Unit | |-----------|--------|-----|-----|------| | Input Voltage | VIN | -0.3 | 30 | V | | Switch Node Voltage | SW | -1 | 30 | V | | Bootstrap Pin Voltage | BST | -0.3 | VSW + 6 | V | | Junction Temperature | TJ | -40 | 150 | °C | | Storage Temperature | TSTG | -65 | 150 | °C | Operating at even 0.1V above the max rating can destroy the IC. The my 9892 datasheet top always places these limits prominently for a reason. Section 3: Pin Configuration – Reading the Top Marking The top marking of the my 9892 IC contains a wealth of information. Here’s how to decode it using the datasheet’s top diagram: Without proper thermal design, the warning about thermal
