UCC3580-2 的说明

The UCC3580 family of PWM controllers is designed to implement a variety of active clamp/reset and synchronous rectifier switching converter topologies. While containing all the necessary functions for fixed frequency, high performance pulse width modulation, the additional feature of this design is the inclusion of an auxiliary switch driver which complements the main power switch, and with a programmable deadtime or delay between each transition. The active clamp/reset technique allows operation of single ended converters beyond 50% duty cycle while reducing voltage stresses on the switches, and allows a greater flux swing for the power transformer. This approach also allows a reduction in switching losses by recovering energy stored in parasitic elements such as leakage inductance and switch capacitance.

The oscillator is programmed with two resistors and a capacitor to set switching frequency and maximum duty cycle. A separate synchronized ramp provides a voltage feedforward pulse width modulation and a programmed maximum volt-second limit. The generated clock from the oscillator contains both frequency and maximum duty cycle information.

The main gate drive output (OUT1) is controlled by the pulse width modulator. The second output (OUT2) is intended to activate an auxiliary switch during the off time of the main switch, except that between each transition there is deadtime where both switches are off, programmed by a single external resistor. This design offers two options for OUT2, normal and inverted. In the -1 and -2 versions, OUT2 is normal and can be used to drive PMOS FETs. In the -3 and -4 versions, OUT2 is inverted and can be used to drive NMOS FETs. In all versions, both the main and auxiliary switches are held off prior to startup and when the PWM command goes to zero duty cycle. During fault conditions, OUT1 is held off while OUT2 operates at maximum duty cycle with a guaranteed off time equal to the sum of the two deadtimes.

Undervoltage lockout monitors supply voltage (VDD), the precision reference (REF), input line voltage (LINE), and the shutdown comparator (SHTDWN). If after any of these four have sensed a fault condition, recovery to full operation is initiated with a soft start. VDD thresholds, on and off, are 15V and 8.5V for the -2 and -4 versions, 9V and 8.5V for the -1 and -3 versions.

The UCC1580-x is specified for operation over the military temperature range of –55°C to 125°C. The UCC2580-x is specified from –40°C to 85°C. The UCC3580-x is specified from 0°C to 70°C. Package options include 16-pin surface mount and dual in-line.

包装类型

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。
