NCP3135MNTXG

NCP3135MNTXG is an integrated synchronous buck converter. It is a fully integrated synchronous buck converter for 3.3V and 5V step-down applications. It can provide up to 5ADC load and 6A instantaneous load current. It supports high efficiency, fast transient response, and provides a power good indicator. The control scheme includes two operation modes: FCCM and automatic CCM/DCM. In automatic CCM/DCM mode, the controller can smoothly switch between CCM and DCM, where the converter runs at a reduced switching frequency with much higher efficiency. The applications include a 5V step-down rail and, a 3.3V step-down rail.

• High efficiency in both CCM and DCM, high operation frequency at 1.1MHz
• Support MLCC output capacitor
• Wide conversion voltage range from 2.9V to 5.5V
• Output voltage range from 0.6V to 0.84 X Vin
• Internal 1ms soft-start, automatic power-saving mode
• Voltage mode control, support pre-bias start-up functionality
• Output discharge operation, over-temperature protection
• Built-in over-voltage, under-voltage and over-current protection
• Power good indicator
• QFN16 package, operation ambient temperature range from -40 to 125°C
