1.5A, 500kHz Step-down Voltage Regulator
LM1572
1.5A, 500kHz Step-down Voltage Regulator
General DescriptionThe LM1572isa 500kHz step-down (buck) switching volt-
age regulator capableof drivingupto 1.5Aintoa load while
occupyinga very small PCB area. Current Mode Control
resultsin superior transient response and regulation overa
wider rangeof operating conditions. National’s advanced
analog bipolar, CMOS plus DMOS process enables high
efficiencyat high switching frequency, and the internal
150mΩ MOSFET switch provides more power froma
smaller package.
The LM1572 has programmable soft-start and frequency
foldbackto limit the inrush current, anda TTL compatible
shutdownfor easy sequencing.It draws 2.3mAof supply
currentin standby mode, and only 26µAin shutdown mode.
The LM1572is availableina TSSOP-16 package withan
adjustable outputor fixed outputsof5V and 3.3V. The ad-
justable version canbeset between 2.42V and5V.
Features 500kHz clock allows small, surface mount components 150mΩ MOSFET switch Guaranteed load currentof 1.5A Current mode control Programmable soft-start Internallyset slope compensation TTL compatible shutdown Fixed5V, 3.3Vor adjustable output Low shutdown supply currentof 26µA Cycle-by-cycle current limit Short-circuit protection and thermal protection TSSOP-16 package
