Triple 800mA synchronous

Downgrade regulator – 2.25MHz

LTC®3545/LTC3545-1 is triple, high efficiency,

Overall synchronization regulator using constant

Frequency, current mode architecture. The regulator operates independently with separate pins. 2.25V to

5.5V input voltage range makes LTC3545/LTC3545-1

Ideal for single lithium-ion battery-powered applications. 

Low ripple pulse skip mode or high efficiency burst mode

Operations are externally selected. PWM pulse skip mode

Operation provides very low output ripple voltage

Breaking mode operation improves efficiency at low output

load.

The switching frequency is set internally to 2.25MHz or

Switching frequency can be synchronized to external

1MHz to 3MHz clock. Power-good indicators are easily allowed

The power of sequencing between the three regulators.

Internal synchronous switches improve efficiency and

Eliminate external Schottky diodes. The low output voltage is

Supports 0.6V feedback reference voltage.

LTC3545-1 uses a instead of synchronization/mode function

The third pgood pin and force burst mode operation.
