LTM4661IY#PBF

LTM4661 is a synchronous step-up switching mode µModule® (power module) regulator. This device 1MHz switching frequency and dual phase single output architecture enable fast transient response to line and load changes and a significant reduction of output ripple voltage. It supports frequency synchronization, PolyPhase® operation and selectable Burst Mode operation. It features a true output disconnect during shutdown and inrush current limit at start-up. It also has short-circuit, overvoltage and overtemperature protection. It is widely used in application such as RF microwave power amplifiers, battery powered DC motors, 3.3V bus telecom transceivers etc.

• Input voltage range is 1.8V to 5.5V
• Output voltage range is 2.5V to 15V
• 4A switch current, dual phase operation
• ±3% maximum total DC output voltage regulation over load, line and temperature
• Output disconnect in shut down, inrush current limit
• External frequency synchronization
• Selectable Burst Mode® operation
• Output overvoltage and overtemperature protection
• Operating temperature is -40°C to 125°C
• Package style is 25-lead BGA
