The UTC UC3750 is a high frequency, micropower, voltage mode Step-down DC-DC Controller IC and is designed for battery operated hand-held electronic products. It CAN provide up to 2.0A loading current with conversion efficiency by connection of appropriate external P-type MOSFET It also CAN be applied to operate for voltage regulation with minimum external components and board space. The UTC UC3750 CAN operate in the constant -frequency PWM (Pulse Width Modulation) mode that provide low output ripple noise in the normal operation and will automatically Switch to PFM(Pulse Frequency Modulation) mode at low output loads for higher efficiency. Moreover, it is ideal for portable applications profited from Chip Enable (CE) to reduce IC off-stage current and integrated feedback resistor network. The UTC UC3750 is suitable for applications, such as PDA, camcorders and digital still camera, hand-held instrument, distributed power system, computer peripheral, conversion from four NiMH or NiCd or one Lithium-ion cells to 3.3V/1.8V.
