Xintao Chip Fht23030 1.1~6.5V Input, 3A Output DC/DC Integrated Molded Adjustable Buck Converter Module

Product Description

XINTAO CHIP FHT23030 1.1~6.5V input, 3A output DC/DC integrated molded adjustable buck converter module

Product Description

Pin	Symbol	Description
1	EN	Enable Pin: Connecting EN to high level turns on the module, while connecting EN to low level turns off the module. When the module is off, this pin has an internal 400KΩ pull-down resistor.
2	VIN	Voltage Input Pin: Connect VIN to the input power supply to power the module.
3	GND	Module Ground.
4 ,5	VOUT	Output Voltage Pin
6	FB	Voltage Feedback Pin: This pin connects to an external voltage divider to adjust the output voltage.
7	PG	Power Good Output Indicator Pin: This pin should be connected to a pull-up resistor to any voltage lower than 6V. If not used, leave it floating.
8	SS	Soft-Start Pin: Connect an external capacitor to ground on this pin to set the rise time of the internal reference voltage.
	Thermal Pad	Exposed Heat Sink Pad: Must be connected to GND. Soldering is required to improve thermal dissipation and mechanical reliability.

Note 1: Stresses above those listed in the "Absolute Maximum Ratings" section may cause permanent damage to the device. Prolonged exposure to any of the Absolute Maximum Ratings conditions may affect device reliability and useful life.
Note 2: The maximum continuous output current may be derated due to the junction temperature of the FHT23030.
Note 3: The performance specifications of the FHT23030 are guaranteed over an internal operating temperature range of -40°C to 125°C. Please note that the maximum internal temperature is determined by specific operating conditions in conjunction with circuit board layout, the rated thermal resistance of the package, and other environmental factors.
