Additional Infomation About Product

L6984 36 V, 400 mA synchronous step-down switching regulator Datasheet - production data Application Battery powered applications (LCM) Sensors (LNM) VFDFPN10 4 x 4 x 1.0 mm E- metering Description VDFPN10 3 x 3 x 1.0 mm The L6984 is a step-down monolithic switching regulator able to deliver up to 400 mA DC. The output voltage adjustability ranges from 0.9 V. The Features fixed 3.3 V V requires no external resistor OUT divider. The Low Consumption Mode (LCM) is 400 mA DC output current designed for applications active during car 4.5 V to 36 V operating input voltage parking, so it maximizes the efficiency at light load Synchronous rectification with controlled output voltage ripple. The Low Noise Mode (LNM) makes the switching Low consumption mode or low noise mode frequency almost constant over the load current 75 A I at light load (LCM V = 3.3 V) Q OUT range, serving low noise application specification 13 A I like car audio/sensors. The PGOOD open Q-SHTDWN collector output can implement output voltage Adjustable f (250 kHz - 600 kHz) SW sequencing during the power-up phase. The Output voltage adjustable from 0.9 V synchronous rectification, designed for high No resistor divider required for 3.3 V V efficiency at medium - heavy load, and the high OUT switching frequency capability make the size of V maximizes efficiency at light load BIAS the application compact. Pulse-by-pulse current 350 mA valley current limit sensing on low-side power element implements Constant on-time control scheme an effective constant current protection.
