资 源 简 介
The LM2696 is a pulse width modulaTIon (PWM) buck regulatorcapable of delivering up to 3A into a load. The controlloop uTIlizes a constant on-TIme control scheme with inputvoltage feed forward. This provides a topology that has excellenttransient response without the need for compensaTIon.The input voltage feed forward ensures that a constantswitching frequency is maintained across the entire VIN range.The LM2696 is capable of switching frequencies in the rangeof 100 kHz to 500 kHz. Combined with an integrated 130mΩ high side NMOS switch the LM2696 can utilize smallsized external components and provide high efficiency. Aninternal soft-start and power-good flag are also provided toallow for simple sequencing between multiple regulators.The LM2696 is available with an adjustable output in an exposedpad TSSOP-16 package.
