600KHZ, 3A STEP-DOWN CURRENT MDOE SWITCHING REGULATOR
DESCRIPTION
As a current mode switching regulator with an integrated
switch, the UTC P1686 is operating at 600kHz with separate sync
and enable functions. In order to avoid frequency beating in noise
sensitive applications the sync function allows customers to
synchronize to a faster clock. Cost effective low power solutions
is considered in the integrated switch ,and so peak switch current
3 amps. Very small passive components is considered in High
frequency of operation. Current mode operation: fast dynamic
response and instantaneous duty cycle adjustment as the input
changes, as a ideal for CPE applications where the input is a wall plug power.
The low shutdown current as ideal for portable applications
when battery life is important.
The UTC P1686 is synchronizable to a frequency from 750kHz to 1.2MHz
