MAX25601A/MAX25601B/

MAX25601C/MAX25601D

Synchronous Boost and

Synchronous Buck LED Controllers

General Description

Beneﬁts and Features

● Integration Minimizes BOM for High-Brightness LED

The MAX25601A/B/C/D is a synchronous boost control-

ler followed by a synchronous buck LED controller. The

4.5V to 40V input voltage range of the boost controller is

ideal for automotive applications, and acts as a pre-boost

power supply for the second-stage buck LED controller.

Driver, Saving Space and Cost

• Wide Input-Voltage Range from 4.5V to 40V

• Wide Boost-Output Range up to 65V

• Programmable Switching Frequency Optimizes

Component Size

• External MOSFETs Can be Sized for Appropriate

Current

• Synchronous Rectiﬁcation Provides High Eﬃciency

and Fast Transient Response

• Average Current-Mode Control for Buck Eliminates

Compensation Components

The synchronous boost is a current-mode controller

that can be be paralleled with another device to provide

higher output power. A SYNCOUT pin provides the clock

to drive the RT/SYNCIN pin of the other device, enabling

two-phase 180-degree out-of-phase operation. The boost

converter can be programmed with a switching frequency

of 200kHz to 2.2MHz. Spread spectrum is included to

reduce EMI. An internal digital soft-start feature is pro-

vided to enable a smooth power up of the boost output.

Protection features like hiccup mode, overvoltage protec-

tion, and thermal shutdown are provided.

● Wide Dimming Ratio Allows High Contrast Ratio

• Analog Dimming and PWM Dimming

• Analog Voltage-Controlled PWM Dimming

● Protection Features and Wide Temperature Range

Increase System Reliability

The synchronous buck LED controller uses Maxim's F

• Short Circuit, Overvoltage, and Thermal Protection

• -40°C to +125°C Operating Temperature Range

Architecture, a proprietary average-current-mode control

scheme to regulate the inductor current at a constant

switching frequency without any control-loop compensa-

tion. Inductor current is sensed in the bottom synchronous

n-channel MOSFET. The device operates over a wide

4.5V to 65V input range at switching frequencies as high

as 1MHz. Both analog and PWM dimming are included.

LED current can be monitored on the IOUTV pin.

Both controllers have high- and low-side gate drivers

with at least 1A peak source and sink-current capabil-

ity. Adaptive non-overlap control logic prevents shoot-

through currents during transition. Both the boost and the

buck faults are monitored on the FLT pin.

The MAX25601A/C is available in a 32-pin SWTQFN

package and the MAX25601B/D is available in a 28-pin

TSSOP package. The 32-pin package features an

additional switch control that can be used in high-beam/

low-beam and heads-up display applications.
