EUP3406 General Description

The EUP3406 is a constant frequency, current mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency. The 2.5V to 5.5V input voltage range makes the EUP3406 ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery or 3-cell NiMH/ NiCd batteries. The output voltage can be regulated as low as 0.6V. The EUP3406 supports up to 600mA load current and can also run at 100% duty cycle for low dropout applications, extending battery life in portable systems.

Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductor and capacitors. The internal synchronous switch increases efficiency while eliminate the need for an external Schottky diode. The EUP3406 is available in a low profile 5 lead SOT package.

EUP3408 General Description

The EUP3408 is a constant frequency, current mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency. The 2.5V to 5.5V input voltage range makes the EUP3408 ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery or 3-cell NiMH/ NiCd batteries. The output voltage can be regulated as low as 0.6V. The EUP3408 supports up to 800mA load current and can also run at 100% duty cycle for low dropout applications, extending battery life in portable systems.

Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency while eliminates the need for an external Schottky diode. The EUP3408 is available in an adjustable version and fixed output voltage of 1.2V ,1.8V and 3.3V.

EUP3410 General Description

The EUP3410 is a current mode, step-down switching regulator capable of driving 2A continuous load with excellent line and load regulation.

The EUP3410 can operate with an input voltage range from 4.5V to 16V and the output can be externally set from 1.2V to 12V with a resistor divider. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25A of supply current.

The EUP3410 requires a minimum number of external components.
