Overview

LX1681/1682 V O LTA G E - M O D E P W M C O N T R O L L E R S T H E I N F I N I T E P O W E R O F I N N O VA T I O N P R O D U C T I O N D A T A S H E E T DESCRIPTION The LX1681/1682 are monolithic, pulsewidth modulator controller ICs.
They are designed to implement a flexible, low cost buck (step-down) regulator supply with minimal external components.
The LX1681 is a non-synchronous controller; the LX1682 has a synchronous driver for higher efficiency.
The output voltage is adjustable by means of a resistor divider to set the voltage between 1.
25V and 4.
5V.
Short-circuit current limiting can be implemented without expensive current sense resistors.
Current is sensed using the...
