TPS630702RNMT Breakout Board

SKU:

The TPS630702 is a high efficiency, low quiescent current buck-boost converter suitable for applications where the input voltage can be higher or lower than the output voltage

Output currents can go as high as 2A in boost mode and in buck mode. The buck-boost converter is based on a fixed frequency, pulse-width modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save Mode to maintain high efficiency over a wide load current range. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery

Board Pinout

PIN Number	PIN Name	Description
1	VIN	Voltage Input Pin (2-16V)
2	GND	Ground
3	VOUT	Adjustable Voltage Output Pin (3.3V – 5V 7.5V – 9V)
4	GND	Ground

PIN Number	PIN Name	Description
1	HIGH – EN – LOW	Regulator Enable Pad. Default Connect to HIGH. If You Want to Off the Regulator Just Solder to LOW.
2	HIGH – V_SEL – LOW	Voltage Select Pad. Default Connect to “LOW”. It means Output Voltage 3.3V. If You Want to Choose Second Voltage, Just Solder to “HIGH”, and Then Solder Only One Pad on “9V – 7.5V – 5V”.
3	HIGH – PS/SYNC – LOW	The PS/SYNC pin has two functions: • switching between forced PWM mode and power save mode. • synchronizing to an external clock applied at pin PS/SYNC. When PS/SYNC is set HIGH, the device operates in power save mode at low output current. The power save mode is disabled when PS/SYNC is set LOW. The device then operates in forced fixed frequency PWM mode independent of the output current. Default Connect to LOW.

PIN Number	PIN Name	Description
1	PG	The PG signal is generated based on the status of the output voltage monitor. The power good circuit operates as long as the converter is enabled and VIN is above the undervoltage lockout threshold.
2	GND	Ground
3	9 V	9V Pad for Second Voltage Selection. Adjusted Resistors for Feedback Pin of Regulator.
4	7.5 V	7.5V Pad for Second Voltage Selection. Adjusted Resistors for Feedback Pin of Regulator.
56	5 V	5V Pad for Second Voltage Selection. Adjusted Resistors for Feedback Pin of Regulator.
