This regulation topology is designed to increase the efficiency of a DC/DC buck converter by disabling the converter during light-load operation and providing a regulated output voltage with a low-Iq LDO. During no-load or light-load conditions, the LDO allows for low-noise, low-Iq output voltage regulation while the DC/DC is disabled. Once the load is engaged, the DC/DC converter can provide high efficiency at high load currents, thereby combining the benefits of both devices.

The Sitara AM437x simplified power sequence feature provides flexibility to power designers. This reference design implementation is a BOM-optimized discrete power solution for the AM437x processor with a minimal number of discrete ICs and basic feature set. The solution represents a baseline of a discrete power solution that can be extended for additional features and capabilities of the AM437x processor.

Возможности:

Simplified, BOM-optimized discrete power solution for the Sitara AM437x processor. AM437x includes an integrated LDO that simplifies processor power sequencing requirements. Systems without controlled power down can greatly benefit from this feature since the integrated LDO always ensures power up/down sequencing is met for VDDS and VDDSHVx supplies The TLV62565 step down converter provides the 3.3 volt supply and the TLV62080 provides the 1.1 volt supply. Two TLV702xx low drop out regulators (LDOs) provide the 1.5-V and 1.8-V supplies. TLV803M voltage supervisor keeps the processor in reset until all rails are operational and to reset the processor when input power is lost. This design is tested and includes schematics, BOM, design guide, and test data.

Эта реализация режима низкого потребления энергии демонстрирует энергопотребление менее 0,1 мВт при сохранении поддержки регенерации памяти LPDDR2 ~1,6 мВт.

Решение состоит из процессора AM437x Sitara, памяти LPDDR2 и контроллера питания TPS65218. Оно оптимизировано для нового режима сохранения энергии совместно с поддержкой унаследованных режимов низкого энергопотребления.

Энергопотребление процессора минимизируется за счет полного отключения питания процессора, за исключением питания часов реального времени (RTC). Переход системы во включенное состояние может быть реализован с помощью одного интерфейсного сигнала (PMIC_PWR_EN), запрограммированного для регистра PMIC.

    • AM437x в режиме RTC-only,
    • TPS65218 в состоянии ожидания,
    • саморегенерация LPDDR2;
  • Система может вернуться в состояние, которое было до включения ожидания
  • Потребление энергии в режиме RTC-only:
    • AM43x + TPS65218: < 0,1 мВт,
    • 2 ГБ LPDDR2 (тип.): 1,6 мВт;
