Description
The MIC38HC44YN is a fixed frequency current-mode PWM controller designed to provide 1A drive current capability. It is an ideal PWM controller where high efficiency is required. The device features undervoltage lockout circuitry that allows for a wider range of operation and decreased startup and operating current, as compared to bipolar UC384x devices operating from a 15V supply. The MIC38HC44YN also has decreased output rise and fall times, and rail-to-rail output capability which increases efficiency, especially at lower supply voltages. It also features a trimmed oscillator discharge current and bandgap reference.
Specifications and features
- Fast 20ns output rise and 15ns output fall times
- Temperature range of –40°C to +85°C
- Low 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
- UVLO with hysteresis
- 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
