1FEATURES DESCRIPTIONThe LM25007isa monolithic step-down switching
Integrated 0.74Ω N-Channel MOSFET Switch regulator featuring all of the functions needed to
• Guaranteed 0.5A Output Current implementa low cost, efficient, power supply.
Ultra-Fast Transient Response Capableof drivinga 0.5A load overa 9V-42V input
voltage range, this deviceis easyto apply andis
• Upto 800kHz Operation providedin the small VSSOP-8 and the thermally
• No Control Loop Compensation Required enhanced WSON-8 packages. Ultra-fast transient
• Vin Feed Forward Provides Constant responseis achieved through the useofa constant
Operating Frequency on-time architecture with Vin feed forward. This
feature provides an almost constant operating
• 2% Accurate 2.5V Feedback from -40°Cto frequency over load and input voltage variations. The
125°C operating frequency can be adjusted witha single
• Highly Efficient Operation resistor. This architectureis easyto use and tolerant
Intelligent Current Limit Protection of component selection. An intelligent current limitis
implementedin the LM25007 with forced off time that
• External Shutdown Control is inversely proportional to Vout thus ensuring
• Thermal Shutdown recovery from fault conditions. The output voltage
VSSOP and Thermally Enhanced WSON may be set from 2.5Vto >30V. To improve efficiency
Packages in light load applications, the Vcc pin can be
connectedto an external voltage sourceto eliminate
the drop through the internal regulator. Additional
TYPICAL APPLICATIONS features include: thermal shutdown, Vcc under-
• 12VDC and 24VDC Distributed Rail Systems voltage lockout, gate drive under-voltage lockout, and
24VAC Systems max duty cycle limiter.
