LM2653 1.5A High Efficiency Synchronous Switching Regulator
Checkfor Samples: LM2653
1FEATURES DESCRIPTIONThe LM2653 switching regulator provides high
Efficiency upto 97% efficient power conversion overa 100:1 load range
• 4Vto 14V Input Voltage Range (1.5Ato15 mA). This feature makes the LM2653 an
1.5Vto 5.0V Adjustable Output Voltage idealfitin battery-powered applications.
0.1Ω Switch On Resistance Synchronous rectificationis usedto achieve upto
300 kHz Fixed Frequency Internal Oscillator 97% efficiency.At light loads, the LM2653 entersa
low power hysteretic or “sleep” modeto keep the
• 7 μA Shutdown Current efficiency high.In many applications, the efficiency
• Patented Current Sensing for Current Mode still exceeds 80%at 15 mA load.A shutdown pinis
Control available to disable the LM2653 and reduce the
Input Undervoltage Lockout supply currentto7µ A.
Output Overvoltage Shutdown Protection All the power, control, and drive functions are
integrated within the ICs. The ICs contain patented
• Output Undervoltage Shutdown Protectioncurrent sensing circuity for current mode control. This
• Adjustable Soft-Start feature eliminates the external current sensing
• Adjustable PGOOD Delay resistor required by other current-mode DC-DC
Current Limit and Thermal Shutdown converters.
The ICs havea 300 kHz fixed frequency internal
APPLICATIONS oscillator. The high oscillator frequency allows the
useof extremely small, low profile components.
• Webpad Personal Digital Assistants (PDAs) Protection features include thermal shutdown, input
undervoltage lockout, adjustable soft-start, cycle by
• Computer Peripherals cycle current limit, output overvoltage and
• Battery-Powered Devices undervoltage protections.
• Notebook Computer Video Supply Handheld Scanners GXM I/O and Core Voltage High Efficiency 5V Conversion Current= 5V,= 3.3V)
