ELM6M003SA5V input 1.5A synchronous step-down DC/DC converter module
ELM6M003SA is a complete 1.5A, synchronous step-down DC/DC convertor module with built-in switching regulator, output capacitor and Inductor for small dimension application.
ELM6M003SA uses constant-on-time (COT) control architecture which simplifies loop compensation and offers excellent load transient response.
ELM6M003SA consumes extremely low 15µA quiescent current hence achieves superior light load efficiency. The high gain error amplifier in the control loop provides excellent load and line regulation.
Proprietary adaptive on-time helps ELM6M003SA to achieve nearly constant switching frequency across load range. ELM6M003SA can operate with input voltage from 2.5V to 6V and provide output range from 0.6V to input level,
thanks to 100% duty cycle operation. ELM6M003SA has cycle-by-cycle current limit and hiccup mode to protect over-load or short circuit fault conditions.
ELM6M003SA is available in compact and low profile 7 leads LGA 3mm × 3mm packages.
