Microchip Technology MCP19124 and MCP19125 PWM Controllers are highly integrated, mixed-signal low-side synchronous controllers that operate from 4.5V to 42V. These controllers allow the development of flexible power supplies that can be configured perfectly to the target application with minimal external components. The MCP19124 and MCP19125 Controllers provide smooth, dynamic transitions from constant-current to constant-voltage operation using the unique control loop architecture. These controllers contain two independent outer control loops that can be configured with separate feedback networks and separate references. The MCP19124 and MCP19125 Controllers are ideal for battery charging applications, LED lighting systems, and low-side switch PWM controllers.
