EC1457

General Description
The EC1457 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5‐ 40V, the
EC1457 delivers 3A of continuous output current with an integrated high side N‐ Channel MOSFET. At light loads,
EC1457 operates in low frequency to maintain high efficiency and low output voltage ripple. Current mode control
provides tight load transient response and cycle‐ by‐ cycle current limiting. The EC1457 guarantees robustness
with input under‐ voltage lockout, start‐ up current run‐ away protection, output short protection, feedback short
protection and thermal protection. The EC1457 is available in 8‐ pin ESOP package.
