SY7072 - High Efficiency 2A Valley Current Synchronous Boost

Description

SY7072 is a high efficient, synchronous, step-up Boost converter designed for one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline Ni-Cd or Ni-MH battery powered applications.

It can convert down to 1.8V input voltage.

It adopts NMOS for the main switch and PMOS for the synchronous switch.

Features

  • 1.8V Minimum Input Voltage.
  • Adjustable Output Voltage from 1.8V to 5.5V.
  • Min 2A Valley Current Limit.
  • 5µA Typical Quiescent Current.
  • Load Disconnect During Shutdown.
  • Low RDS(ON) (Main Switch/Synchronous Switch) at 3.3V Output: 100/170mΩ.
  • Output OVP.
  • Auto Bypass Mode When VIN ≥VOUT.
  • RoHS Compliant and Halogen Free.
  • Compact Package SOT23-6.

SY7072 1.8V Minimum Input and 5. 5V Maximum Output High Efficiency 2A Valley Current Synchronous Boost General Description SY7072 is a high efficient, synchronous, step-up Boost converter designed for one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline Ni-Cd or Ni-MH battery powered applications. It can convert down to 1.8V input voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch. SY7072 can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY7072 enters bypass mode automatically.
