DescriptionThe UCC2808APWTR-2 is one member of the UCC2808 family which is designed as the BiCMOS push-pull, high-speed, low-power, pulse-width modulator device that contains all of the control and drive circuitry required for off-line or dc-to-dc fixed frequency current-mode switching power supplies with minimal external parts count. This device offers a variety of package temperature range options, and choice of undervoltage lockout levels and has some dual output drive stages that is arranged in a push-pull configuration.
Features of the UCC2808APWTR-2 are:(1)dual output drive stages in push-pull configuration; (2)130-A typical starting current; (3)1-mA typical run current; (4)operation to 1-MHz; (5)internal soft start; (6)on chip error amplifier with 2-MHz gain bandwidth product; (7)on chip VDD clamping; (8)output drive stages capable Of 500-mA peak source current, 1-A peak sink current.
The absolute maximum ratings of the UCC2808APWTR-2 can be summarized as:(1)Supply voltage (IDD 10 mA): 15 V;(2)Supply current: 20 mA;(3)OUTA/OUTB source current (peak): -0.5 A;(4)OUTA/OUTB sink current (peak): 1.0 A;(5)Analog inputs (FB, CS): -0.3 V to VDD+0.3 V, not to exceed 6 V;(6)Storage temperature: -65°C to 150°C;(7)Junction temperature: -55°C to 150°C;(8)Lead temperature (soldering, 10 sec.): 300°C.
