Product description
Product features: Intelligent dual-mode high-efficiency conversion, PWM/PFM
automatic switching: PFM mode for light load (quiescent current only 200-600A), heavy load automatically cut PWM mode, comprehensive efficiency 82-93%. Flexible voltage output, Preset
voltage: 5V (jumper selection) Support 1.2 -20V custom output (0805 resistor adjustment). power density, 2A maximum input current + 4A switching capability, 24.4 × 13.7 mm mini size achieves 15W peak power (at 11V input). Performance Measurement Data [
Test condition: 25 | Natural convection cooling ] 3V5V- 0.9AE fficiency 89% | Chip Temperature Rise T=28 5V9V- 0.84AE fficiency 91% | Chip Temperature Rise T=22 Extreme test: 11V12V- 1.38A (15W) for 10 minutes (forced air cooling required) CRITICAL NOTES.
Differential voltage law: Input must be 0.5V output voltage (If output 5V, input 4.5V ), otherwise output voltage is out of control!
Heat dissipation mandatory requirements: Input 7V or output 1A must be added heat sinks Ambient temperature > 40 need to be reduced use It is strictly prohibited to plug and unplug the load with electricity (first disconnect the input power supply) Measure the voltage with a short and thick wire (wire resistance affects the accuracy).
