20V, 20A Monolithic Synchronous Silent Switcher 2 Buck Regulator Reduces EMI & Enables High Power Density Applications
2017-07-24 | ReturnThe LTC7150S’s very low 25ns minimum on-time allows for a high step-down ratio power supply at high frequencies supporting both forced continuous and discontinuous mode operation. The operating frequency is selectable from 400kHz to 3MHz and can be synchronized to an external clock. The LTC7150S’s total differential output voltage accuracy is ±1% over the –40°C to 125°C operating junction temperature range. Additional features include differential remote VOUT sensing directly at the load, PHMODE phase selector pin, accurate 1.2V RUN pin threshold, VIN overvoltage protection, power good and programmable soft-start/tracking.
The LTC7150S is available in a thermally enhanced 42-lead 5mm × 6mm × 1.3mm BGA package, in both RoHS lead-free and leaded SnPb (63/37) finishes. The E and I grades arespecified from –40°C to 125°C operating junction temperature range. The 1,000-piece price starts at $5.60 each for the E grade. All versions are available from stock. For more information, visit www.linear.com/product/LTC7150S.
