SNVS954C –APRIL 2013–REVISED MAY 2013

Wide Input Synchronous Boost Controller with Multiple Phase Capability

Check for Samples: LM5122/LM5122-Q1

FEATURES

APPLICATIONS

•

Available in AEC-Q100 (LM5122-Q1)

Maximum Input Voltage : 65 V

•

12 V, 24 V, and 48 V Power Systems

Automotive Start-Stop

Min Input Voltage : 3.0 V (4.5 V for startup)

Output Voltage up to 100 V

Audio Power Supply

High Current Boost Power Supply

Bypass (V_OUT= V_IN) Operation

DESCRIPTION

The LM5122 is a multiphase capable synchronous

boost

synchronous boost regulator applications. The control

method is based upon peak current mode control.

Current mode control provides inherent line feed-

forward, cycle-by-cycle current limiting and ease of

loop compensation.

1.2 V Reference with ±1.0% Accuracy

Free-Run/Synchronizable Switching to 1 MHz

Peak Current Mode Control

controller

intended

for

high-efficiency

Robust 3 A Integrated Gate Drivers

Adaptive Dead-Time Control

Optional Diode Emulation Mode

Programmable Cycle-by-Cycle Current Limit

Hiccup Mode Overload Protection

Programmable Line UVLO

The switching frequency is programmable up to 1

MHz. Higher efficiency is achieved by two robust N-

channel MOSFET gate drivers with adaptive dead-

time control. A user-selectable diode emulation mode

also enables discontinuous mode operation for

improved efficiency at light load conditions.

Programmable Soft-Start

Thermal Shutdown Protection

Low Shutdown Quiescent Current: 9 μA

Programmable Slope Compensation

An internal charge pump allows 100% duty cycle for

high-side synchronous switch (Bypass operation). A

180º phase shifted clock output enables easy multi-

phase interleaved configuration. Additional features

include thermal shutdown, frequency synchronization,

hiccup mode current limit and adjustable line

undervoltage lockout.
