Introduction
TPS548B22器件是一款具有自适应导通时间D-CAP3模式控制的紧凑型单相降压转换器。该器件针对空间受限类电源系统而设计，可实现高精度、高效率和快速瞬态响应，易于使用，且使用的外部组件较少。 该器件采用全差动传感和集成FET，高侧导通电阻为4.1 mΩ，低侧导通电阻为1.9 mΩ。此外，该器件还具备0.5%的精度和0.9V基准电压，环境温度范围介于 -40°C和 +125°C之间。具有竞争力的特性包括：超低的外部组件数、精准的负载和线路调节、输出电压设定值精度、自动跳过或FCCM工作模式以及内部软启动控制。 TPS548B22器件采用7 mm×5 mm、40引脚、LQFN-CLIP (RVF)封装（RoHs豁免）。 The TPS548B22 device is a high-efficiency, single-channel, FET-integrated, synchronous buck converter. It is suitable for point-of-load applications with 25 A or lower output current in storage, telecomm and similar digital applications. The device features proprietary D-CAP3 mode control combined with adaptive on-time architecture. This combination is ideal for building modern high/low duty ratio, ultra-fast load step response DC-DC converters. The TPS548B22 device has integrated MOSFETs rated at 25-A TDC. The converter input voltage range is from 1.5 V up to 18 V, and the VDD input voltage range is from 4.5 V to 22 V. The output voltage ranges from 0.6 V to 5.5 V. Stable operation with all ceramic output capacitors is supported, because the D-CAP3 mode uses emulated current info
Features

- ±0.5%, 0.9VREF tolerance range: -40°C to +125°C (junction temperature)
- True differential remote sense amplifier
- D-CAP3™ control loop supporting bulk capacitors and/or small MLCCs without external compensation
- Adaptive on-time control with 4 selectable frequency settings: 425kHz, 650kHz, 875kHz, and 1.05MHz
- Temperature compensation with programmable positive/negative current limit and OC clamp
- Selectable hiccup or latch-off OVP or UVP
- VDD UVLO externally adjustable via precision EN hysteresis
- Pre-bias startup support
- Selectable Eco-Mode and FCCM
