LM2575SX-ADJ/NOPB Integrated Circuit ICs

PRODUCT DESCRIPTION
LM2575SX-ADJ/NOPB / SMD/SMT / Texas Instruments / TO-263-5 / Reel







1FEATURES DESCRIPTION 23 The LM2575 series of regulators are monolithic • 3.3V, 5V,
12V, 15V, and Adjustable Output integrated circuits that provide all the active
functions Versions for a step-down (buck) switching regulator, capable of •
Adjustable Version Output Voltage Range, driving a 1A load with excellent line and
load – 1.23V to 37V (57V for HV Version) ±4% regulation. These devices are
available in fixed output Max Over voltages of 3.3V, 5V, 12V, 15V, and an
adjustable output version. – Line and Load Conditions • Specified 1A Output
Current Requiring a minimum number of external components, these regulators are
simple to use and • Wide Input Voltage Range, 40V up to 60V for include internal
frequency compensation and a fixed- HV Version frequency oscillator. • Requires
Only 4 External Components The LM2575 series offers a high-efficiency • 52 kHz
Fixed Frequency Internal Oscillator replacement for popular three-terminal linear •
TTL Shutdown Capability, Low Power Standby regulators. It substantially reduces the
size of the Mode heat sink, and in many cases no heat sink is required. • High
Efficiency • Uses Readily Available Standard Inductors A standard series of
inductors optimized for use with the LM2575 are available from several different •
Thermal Shutdown and Current Limit manufacturers. This feature greatly simplifies
the Protection design of switch-mode power supplies. • P + Product Enhancement
Tested Other features include a specified ±4% tolerance on output voltage within
specified input voltages and APPLICATIONS output load conditions, and ±10% on the
oscillator • Simple High-Efficiency Step-Down (Buck) frequency. External shutdown
is included, featuring Regulator 50 μA (typical) standby current. The output
switch includes cycle-by-cycle current limiting, as well as • Efficient Pre-
Regulator for Linear Regulators thermal shutdown for full protection under fault •
On-Card Switching Regulators conditions. • Positive to Negative Converter (Buck-
Boost)
