5A, 10V, Monolithic Synchronous Step-Down Regulator DESCRIPTION The LTC®3602 is a high efficiency, monolithic synchronous, step-down DC/DC converter utilizing a constant-frequency, current mode architecture.
It operates from an input voltage range of 4.
5V to 10V and provides an adjustable regulated output voltage from 0.
6V to 9.
5V while delivering up to 2.
5A of output current.
The internal synchronous power switch with 65mΩ on-resistance increases efficiency and eliminates the need for an external Schottky diode.
The switching frequency can either be set by an external resistor or synchronized to an external clock.
OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
The LTC3602 can be configured for either Burst Mode operation or forced continuous operation.
Forced continuous operation reduces noise and RF interference, while Burst Mode operation provides the high efficiency at light loads.
In Burst Mode operation, external control of the burst clamp level allows the output voltage ripple to be adjusted according to the requirements of the application.
