LM1572
1.5A, 500kHz Step-down Voltage Regulator
General Description
The LM1572 is a 500kHz step-down (buck) switching volt-
age regulator capable of driving up to 1.5A in to a load while
occupying a very small PCB area. Current Mode Control
results in superior transient response and regulation over a
wider range of operating conditions. National’s advanced
analog bipolar, CMOS plus DMOS process enables high
efficiency at high switching frequency, and the internal
150m
MOSFET switch provides more power from a
smaller package.
The LM1572 has programmable soft-start and frequency
foldback to limit the inrush current, and a TTL compatible
shutdown for easy sequencing. It draws 2.3mA of supply
current in standby mode, and only 26μA in shutdown mode.
The LM1572 is available in a TSSOP-16 package with an
adjustable output or fixed outputs of 5V and 3.3V. The ad-
justable version can be set between 2.42V and 5V.
