LM2695 High Voltage (30V, 1.25A) Step Down Switching Regulator
Checkfor Samples: LM2695
1FEATURES DESCRIPTIONThe LM2695 Step Down Switching Regulator features
Integrated 33V, N-Channel Buck Switch allof the functions neededto implementa low cost,
• Integrated Start-Up Regulator efficient, buck bias regulator capable of supplying
Input Voltage Range: 8Vto 30V 1.25Ato the load. This buck regulator containsa 33V
N-Channel Buck Switch, and is available in the
• No Loop Compensation Required thermally enhanced WSON-10 and HTSSOP-14
• Ultra-Fast Transient Response packages. The hysteretic regulation scheme requires
• Operating Frequency Remains Constant with no loop compensation, resultsin fast load transient
Load Current and Input Voltage response, and simplifies circuit implementation. The
operating frequency remains constant with line and
• Maximum Duty Cycle Limited During Start-Up load variations due to the inverse relationship
• Adjustable Output Voltage between the input voltage and the on-time. The
• Valley Current LimitAt 1.25A current limit detectionis set at 1.25A. Additional
features include: VCC under-voltage lockout, thermal
• Precision Internal Reference shutdown, gate drive under-voltage lockout, and
• Low Bias Current maximum duty cycle limiter.
• Highly Efficient Operation Thermal Shutdown PACKAGE 10-Pin WSON(4 mmx4 mm)TYPICAL APPLICATIONS • 14-Pin HTSSOP• High Efficiency Point-Of-Load (POL) Regulator • Exposed Thermal Pad For Improved Heat• Non-Isolated Telecommunication Buck DissipationRegulator Secondary High Voltage Post Regulator
