LT8692S

42V/2A + 3× 8V/1A, 2MHz Quad Monolithic

Synchronous Step-Down Regulator

FEATURES

DESCRIPTION

Flexible Power Supply System Providing Four

Outputs with a Wide Input Range

The LT^®8692S is a quad channel step-down, current

mode, monolithic buck switching regulator. All regula-

tors are synchronized to a single oscillator with a fixed

frequency of 2MHz. The “S” at the end of the part number

refers to the second-generation Silent Switcher^®technol-

ogy which includes integrated bypass capacitor to deliver

a high frequency and small solution size with excellent

EMI performance. The integrated capacitors also make

it easier to achieve the advertised EMI performance by

reducing layout sensitivity. This performance makes the

LT8692S ideal for noise sensitive applications and envi-

ronments. The highly integrated four-channel solution

saves space and simplifies the design of compact boards.

One High Voltage Synchronous Buck Regulator

3V to 42V Input Voltage Range

Continuous Output Current Up to 2A

High Efficiency Up to 93%

Three Low Voltage Synchronous Buck Regulators

1.2V to 8V Input Voltage Range

Continuous Output Currents Up to 1A

High Efficiency Up to 95%

Silent Switcher^®Architecture

Ultralow EMI/EMC Emissions

Spread Spectrum Frequency Modulation

Ultralow Quiescent Current Burst Mode^®Operation

Burst Mode operation enables ultralow standby current

consumption, forced continuous mode can be used to

control frequency harmonics across the entire output load

range or spread spectrum operation can further reduce

EMI emissions.

9.6μA I Regulating 12V to

IN1

OUT1-4

5V/3.3V/1.8V/1.2V

Output Ripple <10mV

PK-PK

External Synchronization Capability

Forced Continuous Mode Capability

Small Thermally Enhanced 4mm × 3mm 20-Lead

LQFN Package

The fast, clean, low overshoot switching edges enable

high efficiency operation at high switching frequencies,

leading to a small solution size with wide control loop

bandwidth for fast transient response.
