500KHz, 18V, 2A Synchronous Step-Down Converter

1、Description

The LYF98102 is a fully integrated, high-efficiency

2A synchronous rectified step-down converter. The

LYF98102 operates at high efficiency over a wide

output current load range.

This device offers two operation modes, PWM

control and PFM Mode switching control, which

allows a high efficiency over the wider range of the

load.

The LYF98102 requires a minimum number of

readily available standard external components and

is available in a 6-pin SOT23 ROHS compliant

package.
