Tariff Charges
The NCP1593 is a fixed 1 MHz, high output current, synchronous PWM converter that integrates a low-resistance, high-side P-channel MOSFET and a low-side N-channel MOSFET. The NCP1593 utilizes internally compensated current mode control to provide good transient response, ease of implementation and excellent loop stability. It regulates input voltages from 4.0 V to 5.5 V down to an output voltage as low as 0.6 V and is able to supply up to 3 A of load current.The NCP1593 includes an internally fixed switching frequency (FSW), and an internal soft-start to limit inrush current. Other features include cycle-by-cycle current limiting, 100% duty cycle operation, short- circuit protection, power saving mode and thermal shutdown.
- Wide Input Voltage Range: from 4.0 V to 5.5 V
- Internal 90 mO High-Side P-Channel MOSFET and 70 mO Low-Side N-Channel MOSFET
- Fixed 1 MHz Switching Frequency
- Cycle-by-Cycle Current Limiting
- Hiccup Mode Short-Circuit Protection
- Overtemperature Protection
- Internal Fixed SoftStart with External Adjustment
- Start-up with Pre-Biased Output Load
- Adjustable Output Voltage Down to 0.6 V
- Auto Power Saving Mode During Light Load
- 100% Duty Cycle Operation
