MIC38C42/3/4/5 Micrel, Inc. MIC38C42/3/4/5 BiCMOS Current-Mode PWM Controllers General Description Features The MIC38C4x are xed frequency, high performance, cur- Fast 40ns output rise and 30ns output fall times rent-mode PWM controllers. Micrels BiCMOS devices are 40C to +85C temperature range pin compatible with 384x bipolar devices but feature several meets UC284x specications improvements. High-performance, low-power BiCMOS Process Ultralow start-up current (50A typical) Undervoltage lockout circuitry allows the 42 and 44 versions Low operating current (4mA typical) to start up at 14.5V and operate down to 9V, and the 43 and CMOS outputs with rail-to-rail swing 45 versions start at 8.4V with operation down to 7.6V. All 500kHz current-mode operation versions operate up to 20V. Trimmed 5V bandgap reference When compared to bipolar 384x devices operating from a Pin-for-pin compatible with UC3842/3843/3844/3845(A) 15V supply, start-up current has been reduced to 50A typical Trimmed oscillator discharge current and operating current has been reduced to 4.0 mA typical. UVLO with hysteresis Decreased output rise and fall times drive larger MOSFETs, Low cross-conduction currents and rail-to-rail output capability increases efciency, espe- cially at lower supply voltages. The MIC38C4x also features Applications a trimmed oscillator discharge current and bandgap refer- Current-mode, off-line, switched-mode power supplies ence. Current-mode, dc-to-dc converters. The MIC38C4x denotes 8-pin plastic DIP, SOIC, and MSOP Step-down buck regulators packages. MIC384Cx-1 denotes 14-pin plastic DIP and Step-up boost regulators SOIC packages. 8-pin devices feature small size, while 14- Flyback, isolated regulators pin devices separate the analog and power connections for Forward converters improved perfomance and power dissipation. Synchronous FET converters For fast rise and fall times and higher output drive, refer to the MIC38HC4x.
