TL3842P - TI Function Overview

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
<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
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
