Description

The LTC1504CS8 is a self-contained, high-efficiency synchronous buck switching regulator used for DC-DC converter applications. The model combines a pair of on-chip 1.5 Ohm power switches, allowing it to deliver up to 500mA of load current. The regulator's peak efficiency of 92% minimizes heat and wasted power. Moreover, its synchronous buck architecture enables the output to source or sink current, as required, to keep the output voltage in regulation.

Specifications and features

Below are the specifications and features of the LTC1504CS8:

• Output current - 500mA at 3.3V output
• Up to 92% peak efficiency
• 1% trimmed internal reference
• Requires as few as four external components for operation
• Input voltage range of 4V to 10V
• Adjustable current limit
• Small SO-8 package
• Switching frequency of 200kHz, synchronized up to 500kHz

Application Scenarios

The LTC1504CS8 can be used in various portable digital systems, active termination, auxiliary output voltage supplies, and minimum part count or size switchers.
