LTC3119EFE#PBF

LTC3119 is a high efficiency 18V monolithic buck boost converter that can deliver upto 5A of continuous output current. Extensive feature integration and very low resistance internal power switches minimize the total solution footprint for even the most demanding applications. A proprietary 4-switch PWM architecture provides seamless low noise operation from input voltages above, equal to, or below the output voltage. External frequency programming as well as synchronization using an internal PLL enable operation over a wide switching frequency range of 400KHz to 2MHz. It is widely used in application such as wide input range power supplies, 1- to 4-cell lithium battery powered products, RF power supplies, solar battery chargers, system backup power supplies, lead acid to 12V regulator etc.

• Input voltage range is 2.5V to 18V
• Runs down to VIN = 250mV after start-up
• Output voltage range is 0.8V to 18V
• Synchronizable with an external clock upto 2MHz
• Accurate run comparator threshold
• Ultralow noise buck-boost PWM
• Current mode control, maximum power point control
• Power good indicator, internal soft-start
• Operating temperature is -40°C to 125°C
• Packaging style is 28-lead plastic enhanced TSSOP
