APM81803 - Synchronous Buck Regulator

Datasheet Summary

Description

The APM81803 is a highly integrated, 3 A, low EMI, DC-DC regulator module that satisfies demanding power delivery requirements.

The APM81803 includes a high-performance DC-DC regulator IC and two capacitors in a compact 4 mm × 4 mm QFN package.

Features

  • AEC-Q100 Grade 1 qualified.
  • ClearPower module DC/DC converter with internal passive components.
  • VIN Range: 3.5 to 36 V operating, 40 V transient.
  • VOUT: 0.8 to 24 V, ±1.5% accuracy, ‒40°C to 150°C.
  • Up to 3 A of continuous output current.
  • Ultra-Low EMI design and selectable spread spectrum to easily pass CISPR25 Class 5.
  • Low-Power (LP) mode: 6 µA IQ from VIN at no load, automatic transition from LP to PWM mode.
  • Fixed Frequenc.
