MC33363B
High Voltage Switching
Regulator
The MC33363B is a monolithic high voltage switching regulator
that is specifically designed to operate from a rectified 240 Vac line
source. This integrated circuit features an on−chip 700 V/1.0 A
SENSEFETt power switch, 500 V active off−line startup FET, duty
cycle controlled oscillator, current limiting comparator with a
programmable threshold and leading edge blanking, latching pulse
width modulator for double pulse suppression, high gain error
amplifier, and a trimmed internal bandgap reference. Protective
features include cycle−by−cycle current limiting, input undervoltage
lockout with hysteresis, overvoltage protection, and thermal
shutdown. This device is available in a 16−lead dual−in−line and wide
body surface mount packages.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. This device series contains ESD protection and exceeds the following tests:
Human Body Model 2000 V per MIL−STD−883, Method 3015.
Machine Model Method 200 V.
2. Maximum power dissipation limits must be observed.
3. Tested junction temperature range for the MC33363B: Tlow = −25°C Thigh = +125°C
ELECTRICAL CHARACTERISTICS (VCC = 20 V, RT = 10 k, CT = 390 pF, CPin 8 = 1.0 mF, for typical values TJ = 25°C,
for min/max values TJ is the operating junction temperature range that applies (Note 3), unless otherwise noted.)
