The 99.4% max duty cycle lets it run near dropout, useful when the input rail sags close to the output voltage. Switching frequency is programmable from 255 kHz to 530 kHz; higher frequency shrinks the inductor and capacitor but increases switching losses. The two outputs can be phased 180° apart to reduce input ripple current — a real advantage when the input source is a long cable or a battery with high internal impedance. ## Supply range and control features The controller integrates Enable, Power Good, and Soft Start — the soft-start pin sets the output ramp time with a single capacitor.","metaTitle":"LTC3727LXEUH-1#PBF Analog Devices Dual Buck, 2-Phase, 32-QFN","metaDescription":"LTC3727LXEUH-1#PBF dual-output step-down controller, 4-28V input, 2-phase synchronous buck, 255-530kHz, -40 to 85°C, 32-QFN.
