Description
- The TPS54331D is a 3A 570kHz Step-down Converter with Eco-mode™ that integrates a low RDS (ON) high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically activated. Furthermore, the 1µA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots during start-up and transient conditions. A cycle-by-cycle current limit scheme, frequency fold back and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54331 device has been internally optimized to improve thermal performance.
- Adjustable output voltage down to 0.8V
- Integrated 80mR high-side MOSFET supports up to 2A continuous output current
- High efficiency at light loads with a pulse skipping Eco-mode™
- 1µA Typical shutdown quiescent current
- Adjustable slow-start limits inrush currents
- Programmable UVLO threshold
- Overvoltage transient protection
- Cycle-by-cycle current limit, frequency fold back and thermal shutdown protection
- Green product and no Sb/Br
- This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
