FUNCTION DESCRIPTION
PWM Control
The UTC P1786 consists of DC/DC converters which employ a PWM system. In this DC/DC converter, the
pulse width varies in a range from 0 to 100% which is according to the load current. Cause the switching frequency
remains constant the ripple voltage which produced by the switching can be removed easily through a filter.
Therefore, these converters provide a low-ripple power over broad ranges of input voltage and load current.
Under Voltage Lockout
The under voltage lockout circuit makes sure that the outputs of high-side MOSFET driver remain in the off state
after the supply voltage drops below 3.3V. When VCC rises above 3.5V normal operation resumes.
RDS(ON) Current Limiting
The current limit threshold is fixed by the external resistor which is connected from VCC supply to OCSET. An
over-current condition is triggered when the PWM voltage is less than the voltage at OCSET.
ILOAD × RDS(ON) = IOCSET × ROCSET
above formula is setting the current limit value.
