EL7556CM is a DC-DC converter IC manufactured by Elantec (now part of Intersil).

The EL7556CM is a DC-DC converter IC manufactured by Elantec (now part of Intersil). Below are the factual specifications, descriptions, and features of the part:

Specifications:

  • Manufacturer: Elantec (Intersil)
  • Type: Synchronous Buck PWM Controller
  • Input Voltage Range: 4.5V to 25V
  • Output Voltage Range: Adjustable from 0.9V to 5.5V
  • Switching Frequency: 300kHz
  • Output Current: Up to 6A (with external MOSFETs)
  • Efficiency: Up to 95%
  • Operating Temperature Range: -40°C to +85°C
  • Package: 16-SOIC

Descriptions:

The EL7556CM is a high-efficiency, synchronous buck PWM controller designed for step-down DC-DC conversion applications. It integrates control logic, gate drivers, and protection features to regulate output voltage efficiently. The IC requires external power MOSFETs to complete the switching converter circuit.

Features:

  • Synchronous Rectification: Improves efficiency by reducing power loss.
  • Adjustable Output Voltage: Set via external resistors.
  • Soft-Start Function: Reduces inrush current during startup.
  • Under-Voltage Lockout (UVLO): Ensures proper operation within input voltage range.
  • Over-Current Protection (OCP): Safeguards against excessive load currents.
  • Thermal Shutdown: Prevents damage from overheating.
  • Low Dropout Operation: Maintains regulation even when input voltage is close to output.
