LM2596s DC to DC Buck Converter with Display
Product Parameters: Input voltage: 4.0V – 40V; output voltage: 1.25V – 37V; output current: 2A (stable) and 3A max; conversion efficiency up to 92%; output ripple under 30mV; switching frequency: 150KHz; operating temperature: -45°C to +85°C.
Simple Operation: Voltmeter display can be turned off by pressing and holding the switch for 1-4 seconds; simply press the switch again to turn it back on.
Easy to Use: Terminal block allows convenient use without soldering; supports wire bonding points; input voltage must be at least 1V higher than the output voltage.
Output Current: Maximum output current up to 3A; recommended working current is 2A; use a heat sink for output above 2A.
Thoughtful Design: 150KHz internal oscillation frequency ensures low power consumption and high efficiency; if output voltage is equal to input voltage, turn the potentiometer counterclockwise for over 10 turns to adjust.
