Application information
Reset pulse delay Trd is given by:
Equation 2
L5150GJ
trd = 32 x Tosc
The Output Voltage Reset threshold can be adjusted via an external voltage divider R1 + R2
(R1 connected between Res_Adj and V0, R2 connected between Res_Adj and GND) according
to the following formula:
Equation 3
Vthre = [(R1 + R2) / R2] * VRes_adj
The Output Voltage Reset threshold can be decreased down to 3.5 V. If it is needed to
maintain it to its default value (8% below Vo_ref typical), it is enough to connect the Res_Adj
pin directly to GND.
