EUP3476A
3A, 28V, 500kHz Synchronous
Step-Down Converter
DESCRIPTION
The EUP3476A is a 500KHz fixed frequency
synchronous current mode buck regulator. The device
integrates both 135mhigh-side switch and 90m
low-side switch that provide 3A of continuous load
current over a wide operating input voltage of 4.5V to
28V.The internal synchronous power switch increases
efficiency and eliminates the need for an external
Schottky diode. Current mode control provides fast
transient response and cycle-by-cycle current limit.
At heavy load, the EUP3476A operates at a fixed
frequency Pulse-Width Modulation mode for
excellent stability and transient response. At light
load, the EUP3476A will operates at a
Pulse-Skipping mode to save power.
The EUP3476A features short circuit and thermal
protection circuits to increase system reliability.
Externally programmable soft-start allows for proper
power on sequencing with respect to other power
supllies and avoids input inrush current during startup.
In shutdown mode, the supply current drops below
1µA. The EUP3476A is available in SOP-8 package
with the exposed pad.
