Function Documentation

tps6274x_init()

int tps6274x_init	(	tps6274x_t *	dev,
		const tps6274x_params_t *	params
	)

Init converter.

Parameters

[in]	dev	Initialized device descriptor for TPS6274x device
[in]	params	Initialization parameters

Returns

set voltage in mV

tps6274x_load_ctrl()

void tps6274x_load_ctrl	(	tps6274x_t *	dev,
		int	status
	)

Sets ctrl pin high to power a subsystem connected on the load pin.

Parameters

[in]	dev	Device descriptor for TPS6274x device
[in]	status	0 will disable the load, everything else will activate it

tps6274x_switch_voltage()

uint16_t tps6274x_switch_voltage	(	tps6274x_t *	dev,
		uint16_t	voltage
	)

Switch to different voltage level.

Parameters

[in]	dev	Device descriptor for TPS6274x device
[in]	voltage	Voltage to set in mV (needs to be between 1.8V-3.3V

Returns

the voltage that was set in mV
