Bicmos Current Mode Pwm Controller

The Bay Linear B38C42 B38C43 B38C44 B38C45 are fixed frequency and high performance current-mode PWM Controller in BiCMOS. They are pin compatible with all bipolar 384Xs controllers are similar to the MIC38C4X family. These devices are designed for DC-to-DC converter applications and feature a trimmed Oscillator discharge current and bandgap reference. The benefit of the BiCMOS process provides significant performance improvement compared to Bipolar 384X devices. At 15VIN the start-up current is reduced to 50A (typ.) from 0.17 mA with an operating current reduced to 4mA (typ.) from 14mA. Also, quicker output rise and fall times drive larger MOSFET s and Rail-to-Rail output capability improves efficiency, especially lower supply voltages. Major differences between members of these series are the UVLO thresholds. Typical UVLO thresholds of 14.5V (on) and 9V (off) for the B38C42 and B38C44 devices make them ideally suited to off-line applications. The corresponding typical thresholds for the B38C43 and B3845 devcies are 8.4V (on) and 7.6V (off). The B39C4X devices are available in 8 pin DIP and SOIC. By Unkown
