Is there a suitable boost chip recommended for 5V to 13V, 14V to 18V, and 24V to 30V? Of course there is! Today, we will introduce a 30V built-in MOS integrated synchronous boost IC that can be used on mobile power supplies, dedicated 24W boost ICs for lever speakers, and even on large ceiling fans.

CXW independently develops CX9427, which is supplied directly from the original factory, with more cost-effective advantages and more guarantee!

CXW new product launches CX9427 with built-in MOS synchronous boost IC, input 3-30V, output 5-30V, small volume and high efficiency, supporting up to 30W power output, suitable for multi port chargers with PD or QC fast charging, lithium battery boost, and more! Welcome factories to inquire and request samples!

CX9427 Overview:

CX9427 chip is a current mode boost (BOOST) chip with automatic frequency regulation of 600KHz, high efficiency, and wide input range, and has high efficiency synchronous boost function and adjustable current limiting function. The power chip is fully integrated into a low internal resistance 20A power MOSFET, which can achieve high power output while greatly simplifying external circuit design and achieving low power consumption and high efficiency power switching. Users can flexibly establish dynamic loops through external compensation to achieve optimal transient performance under all conditions.

CX9427 chip also includes undervoltage latch, overcurrent protection, and over temperature protection to prevent damage in the event of output overload.

CX9427 is a high-efficiency synchronous boost driver chip:

7.4V to 12V 2A, with an efficiency of up to 95% and a stable output of up to 4A (typical value)

12V to 24V 2A, with an efficiency of up to 94% and a stable output of up to 4A (typical value)

CX9427 Features:

• Fully compliant with Intel Thunderbolt Power Spec

• Input current limiting resistor, flexible setting of maximum output power

• The maximum input current can reach 8A

• Automatic frequency modulation, minimizing power consumption

• Enhanced PWM mode for fast transient response

• 3.0 V-30V wide input range

• Output voltage: 5V To 30V

• When the chip stops working, the current is<1 µ A

CX9427 applies to:

• Thunderbolt interface

• Laptops and tablets

• Hot swappable power management
