SY7072A - High Efficiency 2A Valley Current Synchronous Boost

General Description

SY7072A is a high efficient, synchronous, step-up Boost converter designed for one-cell Li-Ion or Lipolymer, or a two to three-cell alkaline Ni-Cd or NiMH battery powered applications.

It can convert down to 0.85V input voltage.

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

Key Features

  • 0.85V 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.
  • RoHS Compliant and Halogen Free.
  • Auto Bypass Mode When VIN ≥VOUT.
  • Compact Package SOT23-6.

SY7072A 0.85V Minimum Input and 5. 5V Maximum Output High Efficiency 2A Valley Current Synchronous Boost General Description SY7072A is a high efficient, synchronous, step-up Boost converter designed for one-cell Li-Ion or Lipolymer, or a two to three-cell alkaline Ni-Cd or NiMH battery powered applications. It can convert down to 0.85V input voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch. SY7072A can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY7072A enters bypass mode automatically.
