The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.

In this mode the internal power consumption is reduced by using burst mode for loads under 350mA and PWM for loads above 350mA. The drawback is a 1-3 % higher output voltage at low load than full load. Fixed PWM mode: In PWM mode the device accurately regulates the output voltage independently of the load current. The drawback is a higher internal power consumption and shorter battery life at lower loads. Pull down the Mode pad to GND to enter this mode.
