Product Overview
LT1738 is a switching regulator controller designed to lower conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved by controlling the voltage and current slew rates of an external N-channel MOSFET switch. Current and voltage slew rates can be independently set to optimize harmonic content of the switching waveforms vs efficiency. It can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. It utilizes a current mode architecture optimized for single switch topologies such as boost, flyback and Cuk. The IC includes gate drive and all necessary oscillator, control and protection circuitry. It is used in application such as power supplies for noise sensitive communication equipment, EMI compliant offline power supplies, precision instrumentation systems, isolated supplies for industrial automation, medical instruments, data acquisition systems etc.
- Low switching harmonic content, reference voltage is 1.250V
- Independent control of output switch voltage and current slew rates
- Greatly reduced need for external filters
- Single N-channel MOSFET driver, supply current is 12mA typical at (RVSL = RCSL = 17K)
- Easily synchronized to external clock
- Regulates positive and negative voltages
- Easier layout than with conventional switchers
- Max switch frequency is 250KHz typical
- Operating temperature is -40°C to 125°C
- Package style is 20-lead plastic SSOP
