PAM8904

Application Information

Charge Pump Mode Setting

The Charge Pump Mode (CPM) pins EN1 and EN2 are used to set the charge pump into mode 1x V_DD, 2x V_DD, 3x V_DDor they can be used to put

the PAM8904 in to a forced low current shutdown mode.

Shutdown Mode

1x Mode

2x Mode

3x Mode

Care must be taken when using the 3x mode with a V_DDsupply of 5V or more, as this will force the V_OUTto exceed its Absolute Maximum

specification (15V).

2.3V to 5.5V

1x, 2x and 3x

Timing Chart and Device Operation

When one or both of the EN pins are pulled high, the device enters normal operation mode, refer to the above table for the mode selection. Once the

PAM8904 senses a valid signal on the DIN pin, the charge pump will start and provide the desired voltage on the VOUT pin and the output drive

VO1 and VO2 start to function after time t_ONwhich is typically between 270µs and 350µs depending on the mode chosen. Once the input signal on

DIN is removed, the PAM8904 senses this and waits typically 42ms to ensure the signal has been removed. If there is no further valid signal within

the time period t_OFF, the PAM8904 enters into a low current standby mode.
