UM3500 : The UM3500 is a 1.5MHz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The UM3500 can supply 600mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The UM3500 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Pulse Skipping Mode operation at light loads provides very low output ripple voltage for noise sensitive applications. The UM3500 is avai.

UM3501 : UM3501 is a high-efficiency pulse-width-modulated (PWM) step-down DC-DC converter, capable of delivering 600mA output current over a wide input voltage range from 2.5V to 5.5V. The target application of UM3501 is for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within the range such as cellular phones, PDAs and handy-terminals. Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application. The UM3501 automatically turns off the synchronous rectifier while the inductor current is low and enters discontinuous PWM mode. This can increase effi.

UM3502QA : The UM3502QA is a complete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETs, synchronous rectifier and control IC are integrated into a tiny 4mm×4mm×1.05mm QFN package. The UM3502QA is engineered to simplify design and to minimize layout constraints. It is an ideal choice to be used to replace less efficient LDO to achieve improved efficiency in space restricted applications. The UM3502QA is capable of delivering 600mA output current over a wide input voltage range from 2.5V to 5.5V. The UM3502QA is a high-efficiency, step-down DC-DC converter with a constant PWM frequency, current mode architecture. The UM3502QA automatically turns off the synchrono.

UM3503QA : The UM3503QA is a complete 1A, DC/DC step-down power supply intended for low-power applications.

UM3510 : The UM3510 is a high efficiency pulse-width-modulated (PWM) synchronous step-down DC-DC converter with an input voltage range of 2.5V to 6.0V. It provides up to 1000mA output current from a single Li-ion cell. The UM3510 operates at 2.25MHz fixed switching frequency and enters Power Save Mode to maintain high efficiency at light load condition. For low noise applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. The UM3510 enters shutdown mode and consumes less than 1μA when EN pin is pulled low. Other features include lower internal reference voltage with 2% accuracy, over temperature protection and over current protection. The UM3510 is availabl.
