Features & Applications
The MIC38C44-1YM is a BiCMOS, fixed frequency, high performance, current-mode PWM controller with a maximum duty cycle of 50%. Available in surface mount SOIC-14 package.
This device is pin compatible with 384x bipolar devices but feature several improvements. The undervoltage lockout circuitry allows the MIC38C44 to start up at 14.5 V and operate down to 9 V.
Features:
- Fast 40ns output rise and 30ns output fall times
- –40°C to +85°C temperature range meets UC284x specifications
- High-performance, low-power BiCMOS Process
- Ultralow start-up current (50 μA typical)
- Low operating current (4 mA typical)
- CMOS outputs with rail-to-rail swing
- ≥ 500 kHz current-mode operation
- Trimmed 5 V bandgap reference
- Pin-for-pin compatible with UC3842/3843/3844/3845(A)
- Trimmed oscillator discharge current
- UVLO with hysteresis
- Low cross-conduction currents
Applications:
- Current-mode, off-line, switched-mode power supplies
- Current-mode, dc-to-dc converters.
- Step-down “buck” regulators
- Step-up “boost” regulators
- Flyback, isolated regulators
- Forward converters
- Synchronous FET converters
