L6984 Applications
- 600 kHz) Output voltage adjustable from 0.9 V No resistor divider required for 3.3 V VOUT VBIAS maximizes efficiency at light load 350 mA valley current
- heavy load, and the high switching frequency capability make the size of the application pact. Pulse-by-pulse current sensing on low-side power element implemen
