Preliminary Datasheet  
R2A20114AFP/ASP  
Continuous Conduction Mode Interleaving  
PFC Control IC  
R03DS0051EJ0100  
Rev.1.00  
Aug 29, 2011  
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.  
R2A20114AFP/ASP integrates a various kinds of protection circuits, such as the detection circuit of breaking of wire in  
feedback loop, two modes of over voltage protection circuits, over current protection circuit and error output circuit (*1),  
which improve the reliability of the power supply system and reduce the number of component parts on the system.  
Features  
Maximum Ratings  
Supply voltage Vcc: 24 V  
Operating junction temperature Tjopr: from –40 to +150 degrees centigrade  
Electrical characteristics  
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  
Package line-up  
Pb-free LQFP-40 (R2A20114AFP)  
Pb-free SOP-20 (R2A20114ASP)  
Notes: *1 Supported only by R2A20114AFP  
*2 Frequency modulation periods (dfm) of R2A20114ASP are fixed.
