Lzc8650c Ic Datasheet Pdf Best Instant
: Monitored via the FB winding network. Shorted outputs drop the FB pin below 0.7V, causing the chip to enter auto-restart mode. Open outputs cause the FB pin to hit its 3.6V OVP ceiling, stopping the driver before high voltages ruin the primary winding or secondary components. Practical Application and Design Implementation

The LZC8650C is often compared to or considered an equivalent to the , sharing similar operating parameters and package types. Supply Voltage ( VINcap V sub cap I cap N end-sub ): Recommended range of 9.5V to 27V (Absolute Max 33V).
Detects demagnetization of the inductor to enable boundary conduction mode / quasi-resonant switching. Typical Application Circuit
: For high-wattage layouts (e.g., 720mA output drivers), dual parallel high-temperature electrolytic capacitors (rated to 130°C, 8000 hours life) minimize ripple current and survive tight housing enclosures. 720mA output drivers)
The primary difference between the LZC8650B and the LZC8650C is that the 'C' variant features input over-voltage and under-voltage protection, whereas the 'B' variant has a lower slope compensation and can achieve performance below 10% of its rated range.
