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)

LM1875T Texas Instruments IC AMP AUDIO PWR 30W AB TO220-5

Categories Integrated Circuits (ICs) Linear - Amplifiers - Audio Manufacturer Texas Instruments Series- Packaging Tube Part Status Active Type Class AB Output Type 1-Channel (Mono) Max Output Power x Channels @ Load 25W x 1 @ 8 Ohm Voltage - Supply 16 V ~ 60 V, ±8 V ~ 30 V Features Short-Circuit and Thermal Protection Mounting Type Through Hole Operating Temperature 0°C ~ 70°C (TA) Supplier Device Package TO-220-5 Package / Case TO-220-5 Formed Leads Base Part Number LM1875 The LM1875 has a sophisticated thermal protection scheme to prevent long-term thermal stress to the device. When the temperature on the die reaches 170°C, the LM1875 shuts down. It starts operating again when the die temperature drops to about 145°C, but if the temperature again begins to rise, shutdown will occur at only 150°C. Therefore, the device is allowed to heat up to a relatively high temperature if the fault condition is temporary, but a sustained fault will limit the m...
