... At 1.5V input and 3.3V output, the board is capable of 130 mA load current. The EN signal is used to enable and disable the MCP1640 device. When enabled, the MCP1640 will regulate the output voltage. When disabled, the MCP1640 disconnects the path from the input to output for True Output Disconnect Shutdown option. The MCP1640 Single Quadruple-A Battery Boost Converter Reference Design uses this feature to reduce no load Standby current ...

... MCP1640 consumes 0.75 µA typically in Shutdown mode. When MCP1640 is in normal operating mode, the No Load Input Current is approximately 70 µA at 1.5V input. To reduce the average input current of the board, the MCP1640’s EN input is pulsed at a slow rate. Figure 2-3 shows that this current is reduced up to 80% ...

... PIC comparator. The PIC12F617 microcontroller works down to 2.0V V detected, the GP2 pin of the microcontroller will set the EN pin of the MCP1640 high for a short time, to pump up the output capacitor to a 3.3V regulated voltage. After that pulled down again and MCP1640 enters into the True Output Disconnect Shutdown option ...
