ZN1066E

The ZN1066E is a kind of switching regulator control and driver unit. ZN1066E is designed for the general purpose control and drive unit in switching power supplies, transformer coupled DC/DC converters, transformerless voltage doublers, plority converters, motor speed control and other power control applications.

There are some features of ZN1066E as follows: (1)complete PWM power control circuitry; (2)single ended or push-pull totem pole type outputs with ±120 mA capability; (3)0-100% duty cycle control; (4)feedback control guarantees non-overlap of output pulses; (5)no dead time setting required; (6)output frequency adjustable up to 500 kHz; (7)independent control of output voltage and output current; (8)2.6 V stable reference ±50 ppm/; (9)inhibit and synchronising input.

What comes next is about the maximum ratings of ZN1066E: (1)supply current (ICC): 200 mA; (2)main output drive current: 160 mA total; (3)clock output current (sink): 25 mA; (4)reference current (sink): 10 mA; (5)ramp control current: 1 mA; (6)bias sourcing current: 1 mA; (7)operating temperature range: -55 to +125; (8)storage temperature range: -65 to +150.
