WHAT IS THE MCP1256/7/8/9 CHARGE PUMP EVALUATION BOARD?
The MCP1256/7/8/9 Charge Pump Evaluation Board is 
an evaluation and demonstration 
tool for Microchip Technology’s MCP1256/7/8/9 Regulated 3.3V, Low-Ripple Charge Pumps with 
low-operating current SLEEP mode or BYPASS mode. The design provides for dynamic 
versatility.
The MCP1256/7/8/9 Charge Pump Evaluation Board is setup to evaluate simple, stand-alone, 
DC-to-DC conversion. 
Two evaluation circuits are provided, demonstrating the versatility 
of the MCP1256/7/8/9 device family.
 One evaluation circuit utilizes the MCP1256, 
demonstrating the SLEEP mode feature along with a power good indication. The other 
evaluation circuit utilizes the MCP1259, demonstrating the unique BYPASS mode feature, along 
with a low battery indication.
When connected, the MCP1256/7/8/9 devices can be evaluated in a variety of applications.
