The TL2575HV-12IKTTR provides all the active functions needed for an integrated circuit's step-down (buck) switching regulator. It requires four to six external components for operation. It accepts a wide input-voltage range of up to 60 V (TL2575-HV) and is available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, or an adjustable output version. The TL2575HV-12IKTTR has an integrated switch capable of delivering 1 A of load current, with excellent line and load regulation.
Fixed 3.3-V, 5-V, 12-V, and 15-V options with ±5% regulation (maximum) over the line, load, and temperature conditions
Specified 1-A output current
Wide input voltage range: 4.75 V to 40 V (60 V for the HV version)
52-kHz (typical) fixed-frequency internal oscillator
TTL shutdown capability with 50-μA (typical) standby current
Thermal shutdown and current-limit protection with cycle-by-cycle current limiting
Buck and inverting buck-boost power supplies
Motor drives and building automation
Grid infrastructure and factory automation and control
