Maxim Alternatives for the National Semiconductor LM4664

National Semiconductor LM4664

Benefits of the MAX9705 over the LM4664:

• Active Emissions Limiting circuitry (AEL) causes the MAX9705 to emit less EMI than the LM4664
• 1.4W vs. 1.1W output power of the LM4664
• Four different preset gains are available
• SYNC input allows the MAX9705 to be driven from an external clock or in Spread Spectrum Mode (SSM), reducing peak power at the switching frequency
• Lower, 7mA, supply current at V_DD = 5V vs. the LM4664's 8mA

Benefits of the LM4664 over the MAX9705:

• The LM4664 is available in a smaller 1.5mm x 1.5mm package
• LM4664 has higher efficiency, 89% vs. 81% for the MAX9705
