FAN5038M-Current Mode Switching Power Supply Controller
illustrate
FAN5038 provides a complete low-cost power system for DSP and other loads that require high performance. The FAN5038 combines an adjustable switch-mode DC-DC converter, a low-dropout linear regulator as the core power source for I/O power supplies in a space-saving SO-16 package. Simple external circuitry provides power sequencing and independent current limiting. An internal precision voltage reference allows the switcher to be adjusted from 1.5V to 3.6V. With the appropriate external components, the FAN5038 can provide core power up to 13A and I/O power up to 5A, allowing multiple DSPs to power a single device.
