Provides unique features for performance optimization and minimizing system voltage errors
Provides system redundancy with power consumption tracking

Microchip Technology announced the release of a new Digitally Enhanced Power Analog (DEPA) buck controller for DC-DC power conversion.

This new device is characterized by excellent flexibility. This single-chip solution controls DC-DC converters and can accept high-voltage inputs (up to 42V) while simultaneously regulating a wide output voltage range of 0.3V to 16V without external components or drivers.

The PIC® microcontroller embedded in the MCP19122/3 can dynamically adjust operating frequency, overvoltage and undervoltage lockout thresholds, current limit, soft start, voltage or current output setpoint, and maximum duty cycle. This high level of configurability provides many application benefits. For example, the MCP19123 can adjust the output overvoltage lockout to meet USB Power Delivery (PD) requirements while maintaining strict protection limits for each output voltage level.

The MCP19123 buck controller offers many unique features, including a programmable differential input amplifier used to optimize performance and minimize system voltage error. This configurability provides a wide output voltage range commonly found in USB power and battery charger applications. For seamless integration with larger systems, the device may synchronize with an external clock and voltage reference, or provide an internal system clock and reference to another device for synchronization purposes.

In servers or telecommunications equipment, this new device enables seamless startup and can accurately track power consumption across the entire board. For high-power applications, multiple outputs can be operated in parallel to provide system redundancy and enhance system reliability. The MCP19122/3 combines a new level of on-board programmable diagnostics and error detection capabilities, making it ideal for high-performance intelligent power applications.

Rich Simoncic, Vice President of Microchip’s Analog, Power, and Interface business unit, emphasized, “Microchip is one of the few companies that truly understands both analog power control and digital controllers,” adding, “The new combination of digital management and analog power control techniques added to Microchip’s DEPA portfolio provides many application benefits that no other company can offer.”
