Quick Detail:

Low Voltage Synchronous Buck Controller with Adjustable Switching Frequency


Description:

The NCP1575 is a low voltage buck controller. It provides the control for a DC−DC power solution producing an output voltage as low as 0.980 V over a wide current range. It contains all required circuitry for a synchronous NFET buck regulator using the V2 control method to achieve the fastest possible transient response and best overall regulation. The NCP1575 operates at a default switching frequency of 200 kHz, but switching frequency is user−programmable with an additional resistor between ROSC and ground. This device provides undervoltage lockout protection, soft−start, and built−in adaptive nonoverlap and is assembled in an SOIC−8 package.
The NCP1575−based solution requires a bias supply of 12 V, and it can convert from a bulk power supply ranging from 2 V to 12 V.
Conversion from bulk supplies greater than 7 V is best accomplished by using an external doubler circuit to raise the enhancement voltage for the external NFET switches.


Applications:

• Pb−Free Packages are Available
• 0.980 V ±1.0% Reference Voltage
• V2 Control Topology
• 200 ns Transient Response
• Programmable Soft−Start
• 40 ns Gate Rise and Fall Times (3.3 nF Load)
• Adaptive FET Nonoverlap Time
• Default 200 kHz Oscillator Frequency (No External Resistor Required)
• User−Programmable Oscillator Frequency (One External Resistor Required)
• Undervoltage Lockout
• On/Off Control Through Use of the COMP Pin
• Overvoltage Protection through Synchronous MOSFETs
• Synchronous N−Channel Buck Design
• “12 V Only” or Dual Supply Operation
