This device integrates both high-side and low-side MOSFETs, delivering a robust and compact solution for point-of-load regulation in modern vehicle electronics.\u003c\/p\u003e\n\u003cp\u003eThis power IC operates with a wide input voltage range from 3.5V to 36V, with 42V load-dump tolerance, making it suitable for harsh automotive electrical environments. It delivers a continuous output current of 3.5A, with the output voltage available as fixed 3.3V or 5V options, or externally adjustable from 1V to 10V to suit diverse system requirements.\u003c\/p\u003e\n\u003cp\u003eThe switching frequency is resistor-programmable from 220kHz to 2.2MHz and can be synchronized to an external clock, offering flexibility for optimizing efficiency and board space. A 180° out-of-phase clock output allows cascading multiple devices for increased power delivery. The device features three operation modes—skip mode, forced fixed-frequency FPWM mode, and external synchronization—to balance efficiency and EMI performance under various load conditions.\u003c\/p\u003e\n\u003cp\u003eEngineered for automotive reliability, this converter includes comprehensive protection features such as cycle-by-cycle current limiting, thermal shutdown with automatic recovery, and a power-good monitor for easy power-supply sequencing. Spread-spectrum frequency modulation helps reduce EMI emissions, while the low 28µA quiescent current at no load enhances system efficiency in standby applications.\u003c\/p\u003e\n\u003cp\u003eQualified to AEC-Q100 standards and operating over the -40°C to +125°C automotive temperature range, this IC is ideal for distributed DC power systems, navigation units, radio head units, and various engine control module power supplies.\u003c\/p\u003e","brand":"Qlnova","offers":[{"title":"Default Title","offer_id":45422263631981,"sku":null,"price":10.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5950\/8845\/files\/16939A.webp?v=1783047705","url":"https:\/\/qlnova.com\/products\/16939a-36v-3-5a-step-down-converter-2-2mhz-automotive-power-management-ic-with-28%c2%b5a-quiescent-current","provider":"Qlnova","version":"1.0","type":"link"}
