INTRODUCTION
FEATURES
GETTING STARTED
Chapter 2. Installation and Operation
The MCP1603 Tiny Reference Design is designed to demonstrate Microchip's
MCP1603 in a fixed output voltage configuration. The board is designed to
demonstrate how to generate both positive and negative rails using the MCP1603. The
MCP1603 is a 500 mA synchronous buck regulator that features both Pulse Frequency
Modulation (PFM) and Pulse Width Modulation (PWM). The PFM mode is used at light
loads to improve system efficiency while the 2.0 MHz PWM mode is entered at heavy
loads. The transition between PFM and PWM modes automatically occurs without any
external intervention. The MCP1603 is available in both adjustable parts that require
an external divider to set the output voltage and fixed output voltage parts. The high
switching speed and TSOT package (1 mm maximum height) make the MCP1603 ideal
for space constrained applications that require an efficient stepped down voltage.
The MCP1603 Tiny Reference Design has the following features:
• Ultra compact size and low profile 500 mA converter design
• Wide Input voltage range from 2.7V to 5.5V
• Fixed output voltages: 3.3V, 1.2V, 1.8V as well as
• Test points for connecting input voltage source and external load
The MCP1603 Tiny Reference Design is fully assembled and tested for evaluating the
MCP1603 device. The board requires the use of an external input voltage source of
2.7V to 5.5V and an external load capable of 500 mA.
