MAX77540

16V /6A, Dual-Phase High-Efficiency

Buck Converter

General Description

Benefits and Features

The MAX77540 is a high-efficiency step-down converter

with two 3A switching phases. It uses an adaptive COT

(constant on-time) current-mode control architecture and

the two 3A switching phases can be configured as either

one (2Φ, 6A) or two (1Φ, 3A each) outputs. Its wide input

voltage range enables a direct conversion for sub-1V out-

● 4V to 16V Input Voltage Range

● 0.5V to 5.2V Output Voltage Range

● Resistor Configurable Default V

● Two 3A Bucks (1Φ) or One 6A Buck (2Φ)

OUT

● ±0.5% V Accuracy (Default V at 25°C)

OUT

● 94% Peak Efficiency (7.6V , 3.3V

, 1MHz)

puts from 3-cell Li+ batteries, USB PD, and 12V

supply

● Auto SKIP/PWM and Low-Power Mode

● 98% Max. Duty Cycle Dropout Operation

● Programmable Soft-Start/Stop and Ramp-Up/Down

Slew Rates

● Pre-Biased Startup and Active Output Discharge

● Programmable Inductor Peak Current Limits

● 0.5/1.0/1.6MHz Nominal Switching Frequency

● Spread-Spectrum Modulation

rails. The output voltages are preset with resistors and

are further adjustable through an I C-compatible interface.

With 94% peak efficiency, low quiescent current, and com-

pact solution size, the MAX77540 is ideal for battery pow-

ered, space-constraint equipment.

Programmable switching frequency, frequency tracking,

and spread-spectrum allow easier system optimization for

noise-sensitive applications. Dedicated EN, POK, and FP-

WMB pins provide options for direct hardware control,

while more programmable options, such as soft-start/stop

and ramp-up/down slew-rates, are available through I C.

An array of built-in protections insures safe operation un-

der abnormal operating conditions.

● Internal/External Frequency Tracking

● Dedicated EN, POK, and FPWM Pins

● Undervoltage lockout (UVLO), Thermal Shutdown,

and Short-Circuit Protection

● High-Speed I C I/F with 3-Slave Address Options

● 30-WLP (2.51mm x 2.31mm) and 24-FC2QFN (3mm x

3mm) Packages

● Less than 55mm Total Solution Size

Applications

● 2/3-Cell Li+ and USB-C Power Delivery Systems

● Microprocessors, FPGAs, DSPs, and ASICs

● Networking and PCIe /RAID Cards
