ZHCSGU1C September 2017 – October 2021 LM5150-Q1
PRODUCTION DATA
The LM5150-Q1 includes internal feedback resistors which are set based on the VSET pin resistor selection. These feedback resistors are disconnected from the VOUT pin in standby mode to minimize quiescent current. The feedback resistor divider is connected to an internal transconductance error amplifier which features high output resistance (RO = 10 M?) and wide bandwidth (BW = 3 MHz). The internal transconductance error amplifier sources current which is proportional to the difference between the feedback resistor divider voltage and the internal reference. The output of the error amplifier is connected to the COMP pin, allowing the use of a Type 2 loop compensation network.
RCOMP, CCOMP and optional CHF loop compensation components configure the error amplifier gain and phase characteristics to achieve a stable loop response. This compensation network creates a pole at very low frequency (FDP), a mid-band zero (FZ_EA), and a high frequency pole (FP_EA). See Section 9.2.2.8 for more detailed information.
