Product Description

APM81911KNBATR is a highly integrated, 3 A, low EMI, DCDC buck regulator module that satisfies demanding power delivery requirements. The APM81911 includes a high-performance DC-DC regulator IC, two capacitors, and an inductor in a compact 4 mm × 6 mm QFN package.

Product Features

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 Frequency PWM (fOSC): 1 MHz to 2.4 MHz, programmable

Synchronization (1 MHz to 2.4 MHz): PLL-based, fSYNC can be above or below fOSC

CLKOUT: Phase-shifted clock output for reduced EMI in multi-converter systems

Accurate enable input threshold
