LTC3815

6A Monolithic Synchronous DC/DC

Step-Down Converter with PMBus Interface

FEATURES

DESCRIPTION

2.25V to 5.5V Input Voltage Range

The LTC^®3815 is a high efficiency, 6A monolithic synchro-

nous buck regulator using a phase lockable controlled

on-time, current mode architecture. The output voltage

1% Total Output Voltage Accuracy Over

Temperature at V = 3.3V or 5V

Single Resistor-Programmable Output Voltage

PMBus Compliant Serial Interface:

is programmable from 0.4V to 72% of V with a single

external resistor or an external voltage reference through

the reference input (REF) pin. The output voltage can be

margined up or down up to 25% with 0.1% resolution

via a PMBus-compliant serial interface. The serial inter-

face can also be used to read back fault status and both

time-averaged (~4ms) and peak input/output current,

input/output voltage and temperature. System configu-

ration and monitoring is supported by the LTpowerPlay^®

development system.

Programmable Output Voltage Margining:

Up to 25% V

Read back of Average and Peak Temperature,

Current, and Voltage (25Hz Refresh Rate)

Fault Status

Range with 0.1% Resolution

OUT

Phase-Lockable Fixed Frequency Up to 3MHz

Less Than 1ms Power-Up Time

Integrated 13-Bit ADC

Optional External Reference Input

The architecture provides extremely fast transient

response and allows operation at the very low on-times

required to regulate low output voltages at high switching

frequencies. The operating frequency is programmable

from 400kHz to 3MHz with an external resistor or for

noise sensitive applications, it can be synchronized to an

external clock over the same range. The operating supply

voltage range is from 2.25V to 5.5V making it suitable

for operation from 2.5V, 3.3V or 5V rails or Lithium-Ion

batteries.

Pin Selectable Fast-Margining of the Output Voltage

Power Good Flag with Pin Programmable Thresholds

and Filter Delay

Differential Remote Output Voltage Sensing

Master Shutdown Mode: <1μA Supply Current

Clock Out for 2-Phase Operation (12A Output Current)

Available in a Thermally-Enhanced 38-Lead

4mm × 6mm QFN Package
