Descrizione
The TPS54295 is a dual-channel adaptive on-time D-CAP2 mode synchronous buck converter. It helps system designers complete power bus regulator sets for various end equipment with a cost-effective solution using fewer components and lower standby current. The main control loop employs D-CAP2 mode control, enabling fast transient response without external compensation components. Adaptive on-time control provides seamless transition between PWM mode at higher load conditions and Eco-mode operation at light load. Eco-mode enables the TPS54295 to maintain high efficiency under light-load conditions. It is compatible with both low ESR output capacitors such as POSCAP or SP-CAP, as well as ultra-low ESR ceramic capacitors. The device operates efficiently and conveniently with input voltages ranging from 4.5V to 18V. Available in a 4.4mm×5mm 16-pin HTSSOP (PWP) package and a 4mm×4mm 16-pin VQFN (RSA) package, designed to operate over an ambient temperature range of -40°C to 85°C.
Caratteristiche
- D-CAP2 control mode, fast transient response, no external components required for loop compensation, compatible with ceramic output capacitors
- Wide input voltage range: 4.5V to 18V
- Output voltage range: 0.76V to 7V
- High-efficiency integrated FETs optimized for low duty cycle applications – 150mΩ (high-side) and 100mΩ (low-side)
- High initial reference accuracy
- Low-side rDS(ON) lossless current sensing
- Adjustable soft-start
- Non-sinking pre-biased soft-start
- 700kHz switching frequency
- Cycle-by-cycle overcurrent limiting
- Overcurrent limit (OCL), overvoltage protection (OVP), undervoltage protection (UVP), undervoltage lockout (UVLO), and thermal shutdown (TSD) protection
- Adaptive gate drive with integrated bootstrap PMOS switch
- Constant OCP via thermally compensated rDS(ON) with 4000ppm/°C temperature coefficient
- 16-pin HTSSOP package and 16-pin VQFN package
- Automatic skip Eco-mode for high efficiency at light load
Applicazioni
- Point-of-load regulation in low-power systems
- Digital TV power networks
- Home terminal equipment
- Digital set-top boxes (STB)
- DVD players and recorders
- Game consoles and other devices
