Product Information
Product Overview
LTC3115-1 is a high voltage monolithic synchronous buck-boost DC/DC converter. Its wide 2.7V to 40V input and output voltage ranges make it well suited to a wide variety of automotive and industrial applications. A proprietary low noise switching algorithm optimizes efficiency with input voltages that are above, below or even equal to the output voltage and ensures seamless transitions between operational modes. Programmable frequency PWM mode operation provides low noise, high efficiency operation and the ability to synchronize switching to an external clock. Switching frequencies up to 2MHz are supported to allow use of small value inductors for miniaturization of the application circuit. Pin selectable Burst Mode operation reduces standby current and improves light load efficiency which, combined with a 3µA shutdown current, ideally suited for battery-powered applications. Additional features include output disconnect in shutdown, short-circuit protection and internal soft-start.
- 1A output current for VIN ≥ 3.6V, VOUT = 5V, 2A output current in step-down operation for VIN ≥ 6V
- Programmable frequency: 100KHz to 2MHz
- Synchronizable up to 2MHz with an external clock
- Up to 95% efficiency
- 30µA no-load quiescent current in Burst Mode® operation
- Ultralow noise buck-boost PWM
- Programmable input under voltage lockout
- Operating temperature range from -40°C to 125°C
- 20-Lead Plastic TSSOP
