The rad hard ISL70005SEH is the only point-of-load (POL) power solution that reduces size, weight and power (SWaP) by integrating a synchronous buck and low dropout (LDO) regulator in one monolithic IC

rad hard ISL70005SEH是一个通过在一个单片集成电路中集成同步降压和低功耗（LDO）调节器来减小尺寸、重量和功率（SWaP）的负载点（POL）电源解决方案。

The buck regulator uses a voltage mode control architecture and switches at a resistor adjustable frequency of 100kHz to 1MHz. Externally adjustable loop compensation allows for an optimum balance between stability and output dynamic performance. The internal synchronous power switches are optimized for high efficiency and excellent thermal performance.

The LDO is completely configurable independent of the switching regulator. It uses NMOS pass devices and separate chip bias voltage (L_VCC) to drive its gate, enabling the LDO to operate with a very low voltage at the L_VIN input. The LDO can sink and source up to 1A continuously, making it an ideal choice to power DDR memory.

The ISL70005SEH is available in a space saving 28 Ld ceramic dual flat-pack package or in die form. It is specified to operate across a temperature range of TA = -55°C to +125°C.

降压稳压器采用电压模式控制架构，开关的电阻可调频率为100kHz至1MHz。外部可调回路补偿允许在稳定性和输出动态性能之间实现平衡。内部同步功率开关经过优化，可实现高效率和优异的热性能。 LDO可以独立于开关调节器进行配置。它使用NMOS pass器件和独立的芯片偏置电压（L_VCC）驱动其栅极，使LDO在L_VIN输入端以非常低的电压工作。LDO可以连续接收和源高达1A，使其成为驱动DDR存储器的理想选择。 ISL70005SEH可采用节省空间的28 Ld陶瓷双扁平封装或模具形式。规定在TA=-55°C至+125°C的温度范围内运行。
