** LM2574HVN-3.3 Description **
The LM2574HVN-3.3 switching regulator can convert the direct current (DC) voltage from the input to the desired voltage. This switching regulator in on- card switching regulators converts the voltage from a battery or other power source to the voltages required by subsequent systems.
** LM2574HVN-3.3 Features **
• New product available: TPS560430, 36-V, 600-mA synchronous step-down
converter
• 3.3-V, 5-V, 12-V, 15-V, and adjustable output versions
• Adjustable version output voltage range: 1.23 V to 37 V (57 V for HV
Version) ±4% maximum over line and load conditions
• Specified 0.5-A output current
• Wide input voltage range: 40 V, up to 60 V for HV Version
• Requires only four external components
• 52-kHz Fixed-frequency internal oscillator
• TTL shutdown capability, low-power standby mode
• High efficiency
• Uses readily available standard inductors
• Thermal shutdown and current-limit protection
• Create a custom design using the LM2574 with the WEBENCH® Power Designer
** LM2574HVN-3.3 Applications **
• Simple high-efficiency step-down (buck) regulator
• Efficient pre-regulator for linear regulators
• On-card switching regulators
• Positive-to-negative converter (buck-boost)
