LM3481Q Switching Controllers HI EFF LOW-SIDE N CH CONTROLLER

DESCRIPTION
The LM3481 is a versatile Low-Side N-FET high performance controller for switching regulators. It is suitable for use in topologies requiring a low-side FET, such as boost, flyback, SEPIC, etc. The LM3481 can be operated at extremely high switching frequencies in order to reduce the overall solution size. The switching frequency of the LM3481 can be adjusted to any value between 100 kHz and 1 MHz by using a single external resistor or by synchronizing it to an external clock. Current mode control provides superior bandwidth and transient response in addition to cycle-by-cycle current limiting. Current limit can be programmed with a single external resistor.

FEATURES
• LM3481QMM in the VSSOP-10 Package are Automotive Grade Products that are AEC-Q100 Grade 1 Qualified (-40°C to +125°C Operating Junction Temperature)
• 10-Lead VSSOP Package
• Internal Push-Pull Driver with 1A Peak Current Capability
• Current Limit and Thermal Shutdown
• Frequency Compensation Optimized with a Capacitor and a Resistor
• Internal Softstart
• Current Mode Operation
• Adjustable Undervoltage Lockout with Hysteresis
• Pulse Skipping at Light Loads

APPLICATIONS
• Distributed Power Systems
• Notebook, PDA, Digital Camera, and other Portable Applications
• Offline Power Supplies
• Set-Top Boxes
