Description
R2A20114AFP/ASP is a boost converter control IC with PFC (Power Factor Correction). Employing continuous conduction mode interleaving PFC, it performs higher efficiency and lower switching noise even for high power use. Interleaving control of the boost converters, namely, producing 180 degrees phase shift between the output signals (GD1,2) driving the boost converters, enables the system to perform high conversion efficiency and low switching noises and, at the same time, to reduces ripple currents in input and output current and then this allows use of smaller components such as boost inductors, input filters and output capacitors.
Features
• Maximum Ratings
⎯ Supply voltage Vcc: 24 V

⎯ VFB feedback voltage VREF: 2.5 V ± 1.5
⎯ UVLO (Undervoltage Lockout) operation start voltage VH: 10.4 V ± 0.7 V
⎯ UVLO operation shutdown voltage VL: 8.9 V ± 0.5 V
⎯ UVLO hysteresis voltage Hysuvl : 1.5 V ± 0.5 V
• Functions
⎯ Boost converter control with continuous conduction mode
⎯ Interleaving control
⎯ Frequency modulation (*2)
⎯ Brownout
⎯ Phase drop (*1)
⎯ External clock synchronization input
⎯ External clock synchronization output (*1)
⎯ Two modes of over voltage protections
Mode 1: Dynamic OVP preventing over voltage after sudden variation of load.
Mode 2: Static OVP preventing over voltage in the period of normal operation.
⎯ Feedback loop wire breaking/open detector
⎯ Dual over voltage protection circuits (*1): FB and OVP2 terminals
⎯ Current balance control
⎯ Phase 1 and Phase 2 independent over current protection
