BM2P139TF
PWM type DC/DC converter IC Integrated Switching MOSFET for non-Isolated type
本IC作為AC/DC用PWM方式DC/DC轉換器為所有帶插座的產品提供最佳的系統。可輕鬆設計非絕緣的高效率轉換器。內建650V/800V 耐壓啟動電路，有助於實現低功耗。內建電流檢測電阻，可實現小型電源設計。使用電流模式控制，進行逐週期電流限制，發揮頻寬和瞬態回應的優異性能。開關頻率固定為100kHz。輕載時降低頻率，實現高效率。內建跳頻功能，有助於實現低EMI。內建650V/800V耐壓SJ-MOSFET，設計更容易。
