HM1484 Product details

Description

The HM1484 is a current mode monolithic buck switching regulator.Operating with an input range of 4.6-20V, the HM1484 delivers 3A of continuous output current with two integrated N-Channel MOSFETs.The internal synchronous power switches provide high efficiency without the use of an external Schottky diode.At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple.Current mode control provides tight load transient response and cycle-by-cycle current

Features

4.6V to 20V operating input range 3A output current.
Up to 94% efficiency.
High efficiency (>85%) at light load.
Adjustable Soft-Start.
Fixed 340kHz Switching frequency.
Input under voltage lockout.
Available in ESOP8 package.
Start-up current run-away protection.
Short circuit protection.
Thermal protection.
