UCC28083 的说明

The UCC38083/4/5/6 is a family of BiCMOS pulse width modulation (PWM) controllers for dc-to-dc or off-line fixed-frequency current-mode switching power supplies. The dual output stages are configured for the push-pull topology. Both outputs switch at half the oscillator frequency using a toggle flip-flop. The dead time between the two outputs is typically 110 ns, limiting each output’s duty cycle to less than 50%.

The new UCC3808x family is based on the UCC3808A architecture. The major differences include the addition of a programmable slope compensation ramp to the CS signal and the removal of the error amplifier. The current flowing out of the ISET pin through an external resistor is monitored internally to set the magnitude of the slope compensation function. This device also includes an internal discharge transistor from the CS pin to ground, which is activated at each clock cycle after the pulse is terminated. This discharges any filter capacitance on the CS pin during each cycle and helps minimize filter capacitor values and current sense delay.

The UCC38083 and the UCC38084 devices have a typical soft-start interval time of 3.5 ms while the UCC38085 and the UCC38086 has less than 100 µs for applications where internal soft-start is not desired.

The UCC38083 and the UCC38085 devices have the turn on/off thresholds of the 12.5 V / 8.3 V, while the UCC38084 and the UCC38086 has the turn on/off thresholds of 4.3 V / 4.1 V. Each device is offered in 8-pin TSSOP (PW), 8-pin SOIC (D) and 8-pin PDIP (P) packages.

包装方式

您可以根据器件数量选择不同的包装方式,包括完整卷带、定制卷带、剪切带、管装或托盘。

定制卷带是从整盘卷带上剪下来的具有连续长度的剪切带,是一种可以对特定数量提供产品批次及生产日期跟踪的包装方式。根据行业标准,使用黄铜垫片在剪切带两端各连接一个 18 英寸的引带和尾带,以直接送入自动组装机。涉及定制卷带的 TI 订单将包含卷带费用。

剪切带是从整盘卷带上剪下来的特定长度的编带。根据所申请器件数量的不同,TI 可能会使用多条剪切带或多个盒子进行包装。

TI 通常会根据库存情况选择将管装托盘器件以盒装或者管装或托盘形式发货。所有器件均会按照 TI 内部规定的静电放电和湿敏等级保护要求进行包装。
