OB2520 CC/CV Primary-Side (PSR) PWM Controller

Name: OB2520 CC/CV Primary-Side (PSR) PWM Controller
Brand: On-Bright
SKU: OB2520

The OB2520 is a high-precision CC/CV primary-side regulation (PSR) PWM controller from On-Bright for low-power offline (AC/DC) chargers and adapters. Primary-side sensing eliminates the opto-coupler and TL431; it integrates constant-voltage (CV) and constant-current (CC) control with cycle-by-cycle current limit and VDD over-voltage protection, for low component count and high efficiency in a SOT23-6.
