Description
The FSQ0170RNA, FSQ0270RNA, FSQ0370RNA
consists of an integrated current mode Pulse Width
Modulator (PWM) and an avalanche-rugged 700V Sense
FET. It is specifically designed for high-performance off-
line Switch Mode Power Supplies (SMPS) with minimal
external components. The integrated PWM controller
features include: a fixed-frequency generating oscillator,
Under-Voltage Lockout (UVLO) protection, Leading
Edge Blanking (LEB), an optimized gate turn-on/ turn-off
driver, Thermal Shutdown (TSD) protection, and
temperature compensated precision current sources for
loop compensation and fault protection circuitry.
Compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSQ0170RNA,
FSQ0270RNA, FSQ0370RNA reduces total component
count, design size, and weight while increasing
efficiency, productivity, and system reliability. These
devices provide a basic platform that is well suited for the
design of cost-effective flyback converters, as in PC
auxiliary power supplies.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. TA = 25°C, unless otherwise specified.

Notes:
5. Non-repetitive rating: Pulse width is limited by maximum junction temperature.
6. L = 51mH, starting TJ = 25°C.
7. Free standing with no heatsink; without copper clad.
(Measurement Condition - Just before junction temperature TJ enters into OTP.)
8. Measured on the DRAIN pin close to plastic interface.
9. Measured on the PKG top surface.
