RT6575A 技术参数

RT6575A/B

Over-Voltage Protection (OVP) & Under-Voltage

Protection (UVP)

The two channel output voltages are continuously

monitored for over-voltage and under-voltage conditions.

When the output voltage exceeds over-voltage threshold

(113% of VOUT), UGATE goes low and LGATE is forced

high. When it is less than 52% of reference voltage, under-

voltage protection is triggered and then both UGATE and

LGATE gate drivers are forced low. The controller is latched

until ENx is reset or LDO5 is re-supplied.

LDO5 and LDO3

When the VIN voltage exceeds the POR rising threshold,

LDO3 will default turn-on. The LDO5 can be power on by

ENx. The linear regulator LDO5 and LDO3 provide 5V and

3.3V regulated output.

Switching Over

The BYP1 is connected to the Channel 1 output. After the

Channel 1 output voltage exceeds the set threshold

(4.66V), the output will be bypassed to the LDO5 output

to maximize the efficiency.
