2 / 49 page LM27403 SNVS896 A – AUGUST 2013 – REVISED SEPTEMBER 2013 www.ti.com DESCRIPTION (CONTINUED) The LM27403 has a conventional voltage-mode control loop with high gain-bandwidth error amplifier and PWM input voltage feedforward to simplify compensation design and enable excellent transient response throughout the full line voltage and load current ranges. Forced-PWM (FPWM) operation eliminates frequency variation to minimize EMI in sensitive applications. An open-drain Power Good circuit provides power-rail sequencing and fault reporting. Other features include programmable system-level thermal shutdown with automatic recovery, output voltage remote sense, configurable soft-start, monotonic startup into prebiased loads, an integrated bias supply low-dropout (LDO) regulator, external power supply tracking, precision enable with customizable hysteresis for programmable line undervoltage lockout (UVLO), and synchronization capability for beat frequency sensitive and multiregulator applications. The LM27403 is offered in a 4-mm x 4-mm thermally-enhanced WQFN- 24 package with 0.5-mm pitch. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

These are stress ratings only and functional operation of the device at these or any other condition beyond those included under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods of time may affect device reliability. (2) All voltages are with respect to the network ground terminal unless otherwise noted. (3) The SW pin can tolerate negative voltage spikes as low as –10 V and as high as 30 V for a duration up to 10 ns. (4) Body diode of the low-side MOSFET notwithstanding, parasitic inductance in a real application may result in the SW voltage ringing negative. (5) The CBOOT pin can tolerate positive voltage spikes as high as 35 V for a duration up to 10 ns. (6) The human body model (HBM) is a 100-pF capacitor discharged through a 1.5-k Ω resistor to each pin. 2 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: LM27403 |
