2A, 18V, 500KHz,
Synchronous StepDown DC/DC Converter
EC3292A
General Description
Features
The EC3292A is a high-frequency, synchronous,rectified, step-
down, switch-mode converter with internal power MOSFETs.
It offers a very compact solution to achieve a 2A continuous
output current over a wide input supply range, with excellent
load and line regulation.
The EC3292A has synchronous-mode Operation for higher
efficiency over the output current-load range. Current-mode
operation provides fast transient response and eases loop
stabilization.Protection features include over-current protection
and thermal shutdown.
The EC3292A requires a minimal number of readily available,
standard external components and is available in space-saving
TSOT23-6L package.
