General Description

AX3811A develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current.

AX3811A operates over a wide input voltage range from 4.35V to 18V and integrates main switch and synchronous switch with very low R DS(ON) to minimize the conduction loss.

AX3811A adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads.

Key Features

  • Low RDS(ON) for internal switches (top/bottom):140/130 mΩ 4.35-18V input voltage range 2A load current capability Instant PWM architecture to achieve fast transient responses Internal softstart limits the inrush current - 2% 0.6V reference - RoHS Compliant and Halogen Free - Compact package: SOT23-6.
