Description

The XC9702 series is 60V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver FETs.The XC9702 series has operating voltage range of 4.5V~60.0V, the output voltage can be set from 2.5V to 12.0V. It can support300mA as an output current with high-efficiency and stable voltage.The switching frequency is 1.0MHz, and the operation mode can be selected between PWM control and PWM/PFM controlwith the MODE pin. When PWM control is operated, the frequency is constant regardless of the load, so noise countermeasures are easy. PWM/PFM control can achieve high efficiency from light loads to heavy loads.The same part number can be used for multiple power supply lines because the set value of the output voltage can be changed using an external resistor.It is possible to externally adjust the soft-start time longer than the internal soft-start using an external resistor and capacitorconnected to EN/SS pin.In addition, the power good function monitors the state of the output voltage. The soft start external adjustment function andpower good function make it easy to configure the power supply sequence.Built-in protection functions include current limit, over voltage protection, thermal shutdown and Lx short protection for safety operation.
