EUP3216
6A Synchronous Step-Down Converter
DESCRIPTION
The EUP3216 is a synchronous, step-down dc-dc
converter capable of providing up to 6A output current
employing adaptive on-time valley-current mode. The
EUP3216 operates from an input voltage range of 3.3V
to 5.5V and provides a regulated output voltage from
0.6V to 2V. The internal synchronous power switch
increases efficiency and eliminates the need for an
external Schottky diode. The EUP3216 features three
switching frequency setting. It can be externally set for
forced PWM continuous mode or pulse skipping mode.
The EUP3216 integrates internal soft-start function,
droop support, external tracking support, output soft
discharge, integrated bootstrap switch, power good
function, and enable function. EUP3216 features short
circuit and thermal protection circuits to increase
system reliability. Externally MODE pin allows for
frequency and operation mode choice. The EUP3216 is
available in a low profile 20pin 4mmx4mm TQFN
package with the exposed pad.
