General Description

The RT6158A converter is a high efficiency single inductor converter which can operate with wide input voltage 2.5V to 5V such as battery which is higher or lower than the output voltage and it can supply the load current up to 2A.

The maximum peak current in the switches is limited to a typical value of 4.5A.

Feedback loop is internally compensated for both Buck and Boost operation and it provides seamless transition between Buck and Boost modes and optimal transient response.

Key Features

  • Input Voltage Range : 2.5V to 5V.
  • Adjustable Output Voltage : 2.1V to 5.2V by External Divided Resistors.
  • Up to 2A Maximum Load Capability for VIN = 3V, VOUT = 3.5V.
  • Up to 96% Efficiency (VIN = 4.2V, VOUT = 3.5V, ILOAD = 0.5A).
  • OCP, OVP, OTP, UVLO and SCP Function.
  • 2MHz Switching Frequency.
  • 5μA Non-Switching Low Quiescent Current.
  • Forced PWM and Automatic PFM/PWM Mode Selection.
  • Output Fast Discharge Function.
  • Automatic / Seamless Step Up and St.
