LM1572 Description
The LM1572 is a 500kHz step-down (buck) switching voltage 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 150mΩ MOSFET switch...
