Light-Load Regulators Address POL Applications
Using the company’s Simple Light Load Mode (SLLM) technology along with current-mode PWM control, the BD91x Series of point-of-load (POL) step-down switching regulators from ROHM Semiconductor are presented as having an efficiency improvement of up to 200% over devices using standard PWM controllers. The SLLM technique enables BD91x series regulators to seamlessly transfer to / from conventional PWM control depending on load conditions. Available with single- and dual-channel outputs, the RoHS-compliant devices draw virtually zero current in stand-by mode and an output voltage accuracy as low as ±1.5%. From $1, samples available now.
