Description
The MIC38HC45YM TR is a fixed frequency current-mode PWM controller with 1A drive current capability. It is a high-performance, low-power BiCMOS device that is pin-compatible with bipolar UC384x devices. This PWM controller is ideal for applications where high efficiency is required, thanks to its high output drive, fast rise and fall times, and low startup current.
Specifications and Features
- Fast 20ns output rise and 15ns output fall times
- -40°C to +85°C temperature range exceeds UC284x specifications
- Ultralow start-up current (50µA typical)
- Low operating current (4mA typical)
- High output drive (1A peak current, HC version)
- CMOS outputs with rail-to-rail swing
- Current-mode operation up to 500kHz
- Trimmed 5V bandgap reference
- Pin-for-pin compatible with UC3842/3843/3844/3845(A)
- Trimmed oscillator discharge current
- Undervoltage lockout circuitry
- Low cross-conduction currents
Application Scenarios
- 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
