LM2696 Datasheet | Texas Instruments

FEATURES - 2 Input Voltage Range of 4.5V- 24V - Constant On-Time - No pensation Needed - Maximum Load Current of 3A - Switching Frequency of 100 k Hz- 500 k Hz - Constant Frequency Across Input Range - TTL patible Shutdown Thresholds - Low Standby Current of 12 µA - 130 mΩ Internal MOSFET Switch APPLICATIONS - High Efficiency Step-Down Switching Regulators - LCD Monitors - Set-Top Boxes DESCRIPTION The LM2696 is a pulse width modulation (PWM) buck regulator capable of delivering up to 3A into a load. The control loop utilizes a constant on-time control scheme with input voltage feed forward. This provides a topology that has excellent transient response without the need for pensation. The input voltage feed forward ensures that a constant switching frequency is maintained across the entire VIN range. The LM2696 is capable of switching frequencies in the range of 100 k Hz to 500 k Hz. bined with an integrated 130 mΩ high side NMOS switch the LM2696 can utilize small sized external ponents and provide high efficiency. An internal soft-start and power-good flag are also provided to allow for simple sequencing between multiple regulators. The LM2696 is available with an adjustable output in an exposed pad HTSSOP-16 package.
