Certificate:
The TPS54202x is a 4.5V to 30V input voltage range, 2A synchronous buck converter. The device includes two integrated switching FETs, internal loop compensation and 5ms internal soft start to reduce component count.
By integrating the MOSFETs, the TPS54202x achieves the high power density and offers a small footprint on the PCB. TPS542025 has fixed 5V output which saves BOM by further reducing FB resistors. TPS542021 has adjustable output by a different FB resistor configuration.
The TPS54202x operates in pulse frequency modulation for high light load efficiency and reduces the power loss. The frequency spread spectrum operation is introduced for Electromagnetic Interference (EMI) reduction.
Cycle-by-cycle current limit in both high-side MOSFET protects the converter in an overload condition and is enhanced by a low-side MOSFET freewheeling current limit which prevents current runaway. Hiccup mode protection is triggered if the overcurrent condition has persisted for longer than the present time.
- Configured for a wide range of applications
- 4.5V to 30V input voltage range
- Selectable adjustable output (TPS542021), fixed 5V output (TPS542025)
- Up to 2A continuous output current
- 0.6V ± 1.5% reference voltage (25°C)
- Supports low drop out mode
- High efficiency
- Integrated 100mΩ and 60mΩ MOSFETs
- Low 2µA shutdown, 26µA quiescent current
- Pulse frequency modulation (PFM) for high light load efficiency
- Ease of use
- Peak current mode control with internal loop compensation
- Fixed 500kHz switching frequency
- Internal 5ms soft start
- Frequency spread spectrum to reduce EMI
- Overcurrent protection for both MOSFETs with hiccup mode protection
- Non-latched protection for over temperature protection (OTP), overcurrent protection (OCP), overvoltage protection (OVP), and undervoltage lockout (UVLO)
- P2P, B2B with TPS54202
- SOT-23 (6), SOT-563 package
