Features

  • Input voltage: 4.0V ~ 23V
  • Output voltage: 0.8V ~ VCC
  • Duty ratio: 0% to 100% PWM control
  • Oscillation frequency: 300KHz typ.
  • Soft-start, current limit, enable function
  • Thermal shutdown function
  • Built-in internal SW P-channel MOS

UTC P1786 consists of 3A step-down switching regulator control which includes a reference voltage source, oscillation circuit, error amplifier and internal PMOS.

UTC P1786 can provide low-ripple power, high efficiency, and excellent transient characteristics.

An enable function, an over current protect and short circuit protect function are built inside, so the operation frequency can be reduced from 300KHz to 30KHz when OCP or SCP occurs.

The PWM control circuit can vary the duty ratio linearly from 100 down to 0%.

This converter also includes an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup.

An internal compensation block is built in to reduce external component count.

These ICs can work as step-down switching regulators with the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally.
