LM1572 1.5A, 500kHz Step-down Voltage Regulator July 2002 LM1572 1.5A, 500kHz Step-down Voltage Regulator General 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 .

LM1578A/LM2578A/LM3578A Switching Regulator April 1998 LM1578A/LM2578A/LM3578A Switching Regulator General Description The LM1578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost, and inverting configurations. The LM1578A features a unique comparator input stage which not only has separate pins for both the inverting and non-inverting inputs, but also provides an internal 1.0V reference to each input, thereby simplifying circ.

500kHz Step-down Voltage Regulator

LM1572 1.5A, 500kHz Step-down Voltage Regulator July 2002 LM1572 1.5A, 500kHz Step-down Voltage Regulator General 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 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 adjustable version can be set between 2.42V and 5V. Features n 500kHz.
