Vct49x3f Pz F1000 Pin Voltage High Quality -

| Pin(s) | Function | Normal Voltage | Trip Threshold | |--------|----------|----------------|----------------| | 13 | CSP (Current sense positive) | 0V to 100mV | Typical overcurrent threshold = 120mV. | | 14 | CSN (Current sense negative) | -20mV to +20mV | Measures voltage across sense resistor or inductor DCR. |

Some variants utilize a lower 2.5V rail for internal high-speed processing. vct49x3f pz f1000 pin voltage

: This IC typically operates within a range of 2.5V to 3.3V . | Pin(s) | Function | Normal Voltage |

| Pin(s) | Function | Voltage | Frequency | |--------|----------|---------|------------| | 26 | RT (Resistor timing) | ~1.8V (sawtooth) | R from pin to GND sets fsw | | 27 | SYNC (External sync) | 0V or 3.3V clock | Accepts 0.9 MHz to 1.1 MHz, 3.3V logic | : This IC typically operates within a range of 2

While the core runs on 3.3V, the chip often interfaces with the main 5V standby power supply unit (SMPS).
