Microchip Technology MCP16503 (EV05A95A) Evaluation Board
Microchip Technology MCP16503 (EV05A95A) Evaluation Board was developed to evaluate the capabilities of the MCP16503 high-performance Power Management Integrated Circuit (PMIC), designed for general-purpose eMPUs (Embedded Microprocessor Units), that require Dynamic Voltage Scaling (DVS). The adjustability is achieved by using selection resistors for each regulator. The Microchip Technology EV05A95A features four DC-DC buck converters capable of delivering 1A each, two LDOs with 300mA current capability, I2C programmable output voltages, and four operating modes: Active, Low Power, Hibernate, and High-Performance Mode.
Features
- Input voltage range of 2.7V to 5.5V
- Four 1A output current buck channels with 100% maximum duty cycle capability
- 2MHz buck channels, PWM operation
- Two auxiliary 300mA low-dropout linear regulators (LDOs)
- Resistor selectable output voltage for the default startup and I2C output voltage configuration following system startup (DVS)
- Adjustable output voltage from 0.6V to 1.85V (only for Buck2, 3 and 4)
- Adjustable output voltage from 1.2V to 3.7V (only for Buck1, LDO1 and LDO2)
- MPU-specific built-in default channel sequencing and nRSTO assertion delay
- Shutdown input pin (EN)
- Support of MPU hibernate, low-power, and high-performance modes with DVS
- 1MHz I2C interface for programming and diagnostics
- Low noise, forced PWM (FPWM), and low IQ, light load, high-efficiency mode available
- I2C-selectable displacement (±16.5%) of PWM switching frequency
- Less than 300μA low-power mode typical quiescent current
- 10μA maximum shutdown current (VIN = 4.5V, TJ = +105°C)
- Thermal shutdown and current limit protection
- User-programmable overcurrent fault response
Applications
- High-performance, general-purpose MPUs
- µC/µP, FPGA, and DSP power
