User Manual

(VDD_LDO1) to VDD_SYS_M of DA9070.

Install J11 jumper will connect LDO_2 input

(VDD_LDO2) to VDD_SYS_M of DA9070.

+ and - are terminals for connecting external load to

the Boost output; When BST_LD (pin 1) is short to +

pin on J12, the on-board load resistor will be used as

the Boost output load. S+ and S- are kelvin sense

points for the Boost output. For output voltage

measurement during efficiency test, S+ and S- should

connect to multi-meter for better accuracy.

Sense points. For probe only.

DA9070 power input (VDD_PWR) supply selection

and voltage sense. VDD_PWR can directly connect

to the 5V_USB rail by shorting J14 pin-1 to pin-2;

VDD_PWR can also connect to the 5V_USB rail

though load switch U1 by shorting J14 pin-2 to pin-3.

The load switch is controlled by the MCU during

battery profiling. For evaluation use jumper positions

1 and 2. J14-S+ and J14-S- pins are kelvin sense

points of DA9070 input VDD_PWR.

S+ and S- are kelvin sense points for DA9070

VDD_SYS.

Sense points. For probe only.

+ and - are terminals for connecting an external load

to DA9070 LDO0 output; When pin-1 is shorted to the

+ pin on J18, the on-board load resistor will be used

as the LDO0 output load.

+ and - are terminals for connecting external load to

DA9070 LDO1 output; When pin-1 is shorted to + pin

on J19, the on-board load resistor will be used as the

LDO1 output load.

+ and - are terminals for connecting external load to

DA9070 LDO2 output; When pin-1 is shorted to + pin

on J20, the on-board load resistor will be used as the

LDO2 output load.

+ and - are terminals for connecting an external load

to DA9070 Buck output; S+ and S- are kelvin sense

points for DA9070 Buck output. For output voltage

measurement during efficiency test, S+ and S- should

connect to multi-meter for better accuracy.
