mlab-modules/tps63060v01

The MLAB TPS63060V01A module is a versatile voltage converter based on the TPS63060 IC from Texas Instruments. It offers selectable output voltages (3.3V or 5V), flexible activation, power-saving mode, and can be synchronized with an external clock.

MLAB TPS63060V01A Module

The MLAB TPS63060V01A module is based on TPS63060 integrated circuit from Texas Instruments. This circuit is a synchronous step-down (buck-boost) converter, capable of regulating the output voltage whether the input voltage is either higher or lower than the output voltage.

TPS63060

The TPS63060 is a highly efficient, fully integrated, synchronous buck-boost converter designed for a wide range of applications. This circuit has an internal switching transistor, which allows it to achieve high efficiency at low loads.

The TPS63060 operates in automatic PFM/PWM switching mode, switching between PFM (Pulse Frequency Modulation) mode at low loads for efficiency optimization, and PWM (Pulse Width Modulation) mode at higher loads for better voltage regulation.

Basic Parameters:

• Input voltage: 2.5 V to 12 V
• Output voltage: 2.5 V to 8 V
• Maximum current for internal transistor: 2 A
• Output voltage selectable at 3.3 V or 5 V (by jumper placement)
• Pin for converter activation: EN
• Pin for power saving mode and synchronization: PS/SYNC

Users can choose between an output voltage of 3.3 V or 5 V using a jumper setting.

A significant feature of the module is the ability to activate and deactivate the converter via the EN (enable input) pin. This is especially useful in applications where power is supplied by batteries, and there is a need to protect them from deep discharge.

A unique feature of the module is also the presence of the PS/SYNC pin, labeled as SN. This allows the power saving mode of the converter to be activated if the current draw is less than 100 mA. This pin can also be used to synchronize the converter with an external clock signal.

Possible Applications

Due to its range of input and output voltages and the ability to regulate, this module is suitable for various applications. It can be used to power low voltage devices from higher voltage batteries or vice versa. Its versatility makes it suitable for a wide range of devices from mobile devices to IoT applications to industrial systems. The power saving mode and the ability to activate/deactivate the converter also support its use in devices where power consumption efficiency is important.

tps63060v01's Issues

Screws connected to GND

Šrouby modulu jsou chybně připojeny k základní desce (GND), to je pro napájecí modul nepraktické, protože to vytváří zemní smyčky přes které se pak dále šíří rušení.

Inaccurate voltage output

Výstupní napětí z modulu má poměrně výrazný rozptyl hodnot, který komplikuje konstrukci některých zařízení. Pozorovaný rozptyl hodnot byl od 3.2V do cca 3.5V.

Je možné že za problémem stojí nepřesnost hodnot rezistorů použitých v děliči. Druhou možností je nepřesnost zpětné vazby použitých kusů IO. Případně to může být kobinace obou těchto možností. Důsledkem je že např. v konstrukci https://github.com/ODZ-UJF-AV-CR/Li-ion-Charger jsou překročeny maximální provozní napětí displeje.
