Single Cell Li-Battery PWM Charger and Power System Management IC
AXP202
when the output voltage is set above 2.5V，2.2uH inductors is recommended; when the output voltage
is set under 2.5V，4.7uH inductors is recommended. Besides, the inductor saturation current should be
larger than 50% of the largest demanded current in power circuitry.

LDO 1
LDO1 is always on and can be used to supply continuous power for application RTC with 30mA drive
ability 30mA.
LDO2/3/4
LDO2/4 output noise is as low as 18uVrms，and can be used to supply power for analog circuits of
application system. LDO3 can supply power for systems like SRAM or PLL with 200mA drive ability.
LDO5
LDO5 also features the low noise design, and its drive ability is 50mA。
Soft Start
All DC-DCs and LDOs support soft start which can avoid the impact of dramatic current change on
the input path in system boot stage.
