Description of operations

1) Shutdown

If the EN input pin set to low (<0.4V), all circuit are shut down and the regulator is standby mode.

Do not leave the EN pin floating.

2) Soft start function

The regulator has a soft start circuit that reduces in-rush current at start-up. Typical start up times with a 4.7uF output

capacitor is 120usec.

3) Current limit

The BZ6Axx06GM has a current limit circuit that protects itself and external components during overload condition.

4) Under Voltage Lock Out (UVLO)

The BZ6Axx06GM has a Under Voltage Lock Out circuit that turn off device when VIN>2.05V(typ.)

5) FORCED PWM MODE

Setting MODE pin high (>1.4V) places the regulator in forced PWM.This control provides noise reduction and output

stability.

Do not leave the MODE pin floating.

6) TSD

The BZ6Axx06GM has a thermal shutdown feature to protect the device if the junction temperature exceeds 150

℃

.In

thermal shutdown, the DRIVER is disabled.

This circuit is only to cut off the IC from thermal runaway, and has not been design to protect or guarantee the IC. Therefore,

the user should not plan to activate this circuit with continued operation in mind.
