Informace o produktu
Přehled produktu
The TL3842P is a current-mode PWM Controller provides the features that are necessary to implement off-line or DC-to-DC fixed-frequency current-mode control schemes with a minimum number of external components. Some of the internally implemented circuits are an under-voltage lockout (UVLO), featuring a start-up current of less than 1mA and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator (that also provides current-limit control) and a totem-pole output stage designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the OFF state.
- Optimized for Off-line and DC-to-DC converters
- <lt/>1mA Low start-up current
- Automatic feed-forward compensation
- Pulse-by-pulse current limiting
- Enhanced load-response characteristics
- Under-voltage lockout with hysteresis
- Double-pulse suppression
- High-current totem-pole output
- Internally trimmed band gap reference
Výstrahy
Toto zařízení má omezenou zabudovanou ESD ochranu, vodiče by měly být zkratovány, nebo zařízení umístěno ve vodivé pěně během uskladnění nebo transportu, aby bylo zabráněno poškození MOS hradel.
