Description

The MCP16503 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), requiring Dynamic Voltage Scaling (DVS). The adjustability is achieved by using selection resistors for each regulator. The device features 4 DC-DC buck converters capable of delivering 1A each, 2 LDOs with 300mA current capability, I2C programable output voltages and 4 operating modes: Active, Low Power, Hibernate and High-Performance Mode.

Features

The MCP16503 Evaluation Board (EV05A95A) has the following features:

Input Voltage: 2.7V to 5.5VFour 1A Output Current Buck Channels With 100% Maximum Duty Cycle Capability2 MHz Buck Channels PWM OperationTwo Auxiliary 300 mA Low Dropout Linear Regulators (LDOs)Resistor Selectable Output Voltage for the default start-up 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)Shutdown Input Pin (EN)MPU-Specific Built-in Default Channel Sequencing and nRSTO Assertion DelaySupport of MPU Hibernate, Low-Power and High-Performance Modes With DVS1 MHz I2C Interface for Programming and DiagnosticsLow Noise, Forced PWM (FPWM) and Low IQ, Light Load, High-Efficiency Mode AvailableI2C-Selectable Displacement (±16.5%) of PWM Switching FrequencyLess Than 300 μA Low-Power Mode Typical Quiescent Current10 μA Maximum Shutdown Current (VIN = 4.5V, TJ = +105°C)Thermal Shutdown and Current Limit ProtectionUser-Programmable Overcurrent Fault Response

Typical applications

  • High-performance, General Purpose MPUs
  • µC/µP, FPGA and DSP Power
