Overview

Description

TPS54821RHLT is a Texas Instruments DC-DC buck regulator IC intended for point‑of‑load/VRM applications. It provides a regulated low‑voltage output from a higher input supply and typically includes an integrated switching element with control logic, plus external feedback to set the output voltage. Key features usually include overcurrent and thermal protection, soft-start, enable control, and adjustable switching frequency. The RHLT suffix denotes a specific package/temperature/reel option for this part variant. It is used with external components (inductor, input/output capacitors, and feedback resistors) to implement a wide range of low‑voltage rails for CPUs, FPGAs, memory, and other embedded/industrial systems. For exact electrical specs, pinout, and reference designs, consult the TPS54821RHLT datasheet.

Features

TPS54821RHLT features (highlights):
- 2-phase interleaved, synchronous buck regulator with integrated high-side and low-side MOSFETs
- Wide input range: 4.5 V to 18 V
- Output voltage adjustable via feedback network; supports remote sensing and voltage tracking
- High efficiency from synchronous rectification and robust transient response
- Multi-phase operation to supply high-current loads and reduce ripple
- Comprehensive protections: overcurrent/short-circuit, undervoltage lockout, overtemperature
- Enable control, soft-start sequencing, and power-good signaling
- Compact RoHS-compliant package suitable for dense board layouts

Package

TPS54821RHLT uses a 28-pin HTSSOP package with exposed pad (RoHS-compliant).

Pinout

- Pin count: 28 pins (28-pin package, e.g., HTSSOP/VQFN variant).
- Function: Dual-channel synchronous buck regulator controller with integrated gate drivers. It drives two high-side/low-side FETs for two-phase step-down regulation, with features such as adjustable switching frequency, enable, soft-start, power‑good, and protections (OC/OV/OT).

Manufacturer
