FEATURES  
DESCRIPTION  
The TPS65300-Q1 power supply is a combination of  
a single switch-mode buck power supply and three  
linear regulators. This is a monolithic high-voltage  
switching regulator with an integrated 1.2-A peak  
current switch, 45-V power MOSFET, and one low-  
voltage linear regulator and two voltage-regulator  
controllers.  
Input VIN Range 5.6 V to 40 V, With Transients  
up to 45 V  
All Outputs Support Ceramic Output  
Capacitors for Stability  
Switch-Mode Regulator With Integrated High-  
Side Switch  
Recommended Switch-Mode Frequency  
Range 2 MHz to 3 MHz  
The device has a voltage supervisor which monitors  
the output of the switch-mode power supply, the 3.3-  
V linear regulator, and the 1.2-V linear regulator. An  
external timing capacitor is used to set the power-on  
delay and the release of the reset output nRST. This  
reset output is also used to indicate if the switch-  
mode supply, the 3.3-V linear regulator supply, or the  
1.2-V linear regulator supply is outside the set limits.  
The 5-V regulator tracks the 3.3-V linear regulator  
within the specified limits.  
Overcurrent Protection and 1.2-A Peak  
Switch Current  
One Linear Regulators and Two Linear  
Regulator Controllers With 0.8-V ±1.5%  
Reference  
Status Indicator Output of IGN_EN Input  
Soft Start on Ignition (IGN_EN)/Enable Input  
(EN) Cycle  
The TPS65300-Q1 has a switching frequency range  
from 2 MHz to 3 MHz, allowing the use of low-profile  
inductors and low-value input and output ceramic  
capacitors. External loop compensation gives the  
user the flexibility to optimize the converter response  
for the appropriate operating conditions.  
External Clock Input for Synchronization  
Programmable Power-On-Reset Delay, Reset-  
Function Filter Timer for Fast Negative  
Transients  
Voltage Supervisor for the Following Supplies  
This device has built-in protection features such as  
soft start on IGN_EN ON or enables cycle, pulse-by-  
pulse current limit, thermal sensing, and shutdown  
due to excessive power dissipation.
