1 / 77 page  This is information on a product in full production. April 2015 DocID027738 Rev 2 1/77 A6985F 38 V 500 mA synchronous step-down switching regulator with 30 µA quiescent current Datasheet - production data Features AECQ100 qualification 0.5 A DC output current 4 V to 38 V operating input voltage Low consumption mode or low noise mode 30 µA IQ at light-load (LCM VOUT = 3.3 V) 8 µA IQ-SHTDWN Fixed output voltage (3.3 V and 5 V) or adjustable from 0.85 V to VIN Adjustable fSW (250 kHz - 2 MHz) Embedded output voltage supervisor Synchronization Adjustable soft-start time Internal current limiting Overvoltage protection Output voltage sequencing Peak current mode architecture RDSON HS = 360 m, RDSON LS = 150 m Thermal shutdown Applications Designed for automotive systems Battery powered applications Car body applications (LCM) Car audio and low noise applications (LNM) Description The A6985F automotive grade device is a step- down monolithic switching regulator able to deliver up to 0.5 A DC. The output voltage adjustability ranges from 0.85V to VIN. The 100% duty cycle capability and the wide input voltage range meet the cold crank and load dump specifications for automotive systems. The “Low Consumption Mode” (LCM) is designed for applications active during car parking, so it maximizes the efficiency at light-load with controlled output voltage ripple. The “Low Noise Mode” (LNM) makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the low noise application specification like car audio. The output voltage supervisor manages the reset phase for any digital load (µC, FPGA). The RST open collector output can also implement output voltage sequencing during the power-up phase. The synchronous rectification, designed for high efficiency at medium - heavy load, and the high switching frequency capability make the size of the application compact. Pulse by pulse current sensing on both power elements implements an effective constant current protection. HTSSOP16 (RTH = 40 °C/W) www.st.com |
