Description
The IRS2505 is a control IC for boost-type
PFC circuits operating in critical-conduction
mode. The IC incorporates a free-running
frequency oscillator with on- and off-time control
of the boost power MOSFET without the need for
a secondary winding. Also included in the design
is over-voltage protection of the DC bus and
cycle-by-cycle over-current protection of the
power MOSFET. Micro-power start-up current and
an internal 20.8V zener clamp at VCC are
provided to simplify the external VCC supply
circuitry. ESD and latch immune CMOS
technology enables a rugged monolithic IC
construction.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may
occur. All voltage parameters are absolute voltages referenced to COM, all currents are
defined positive into any pin. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions.

† This IC contains a voltage clamp structure between the chip VCC and COM which has a
nominal breakdown voltage of 20.8V. This supply pin should not be driven by a DC, low
impedance power source greater than the VCLAMP specified in the Electrical
Characteristics section.
This IC contains a voltage clamp structure between the CMP and COM which has a
†† nominal breakdown voltage of 10.2V. This pin should not be driven by a DC, low
impedance power source greater than the VZCMP specified in the Electrical
Characteristics section.
