Product details
Overview
TPS62A01DRLR from Texas Instruments is a 1A, synchronous buck DC/DC converter in SOT-563 (6-pin) package, operating from 2.5V–5.5V input to deliver adjustable 0.6V–VIN output with 2.4MHz fixed-frequency PWM and power-save mode. It integrates 180mΩ/120mΩ HS/LS MOSFETs, delivers 1% FB accuracy over –40°C to 125°C, and features power-good (PG) output for sequencing in compact point-of-load applications such as IP network cameras and solid-state drives.
For engineers reviewing the TPS62A01DRLR datasheet, TPS62A01DRLR pinout, TPS62A01DRLR application, or TPS62A01DRLR equivalent, key selection criteria include its 1A output capability in ultra-small 1.6mm × 1.6mm SOT-563, <23µA quiescent current, 100% duty-cycle low-dropout operation, and pin-to-pin compatibility with TLV62585 - critical for space-constrained battery-powered and embedded systems.
Technical Context
The TPS62A01DRLR uses adaptive off-time peak-current control to maintain stable 2.4MHz switching across input/output/load variations. Its dual-mode operation - PWM at medium/heavy loads and automatic power-save mode (PSM) at light loads - ensures high efficiency (>90% at 1A, 3.3VIN/1.8VOUT) across the full 0–1A range.
It implements HICCUP short-circuit protection (32-cycle lockout), thermal shutdown at 170°C with 20°C hysteresis, and internal soft-start (1ms ramp). The PG pin provides open-drain status indication tied to FB voltage thresholds (93.5%/96%), enabling reliable rail sequencing without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, USB, and 3.3V/5V rails without pre-regulation. |
| Output Current | 1A continuous - sufficient for core logic, FPGA I/O, or microcontroller domains in compact designs. |
| Switching Frequency | 2.4MHz fixed - enables use of small 1.0µH inductors and ceramic capacitors for minimal board area. |
| Quiescent Current | <23µA - extends battery life in always-on or low-duty-cycle IoT endpoints. |
| Feedback Accuracy | ±1% over –40°C to 125°C - ensures stable output regulation under thermal stress in industrial environments. |
| High-Side RDS(on) | 180mΩ at 5V - minimizes conduction loss and improves efficiency at mid-load conditions. |
| Power-Good Threshold | 93.5% (falling), 96% (rising) - provides clean, glitch-immune sequencing signal for downstream ICs. |
Pinout & Package
SOT-563 (6-pin) package: 1.60mm × 1.60mm footprint, 0.5mm pitch, thermally enhanced exposed pad (not electrically connected per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Primary return path for power stage and control circuitry; requires low-impedance PCB connection to minimize noise and thermal resistance. |
| SW (Pin 2) | Switch node | Connects to inductor and internal HS/LS FETs; high di/dt node requiring tight layout and minimized loop area to reduce EMI. |
| VIN (Pin 3) | Input supply | Accepts 2.5V–5.5V; must be decoupled with 4.7µF ceramic capacitor placed adjacent to this pin and GND. |
| EN (Pin 4) | Enable input | Active-high logic control (1.2V threshold); must be pulled high or driven - never left floating to prevent erratic startup. |
| FB (Pin 5) | Feedback input | Monitors output via resistor divider; 600mV nominal reference enables precise VOUT setting from 0.6V upward. |
| PG (Pin 6) | Power-good open-drain | Indicates regulated output (93.5–96% of target); requires external pullup ≤5.5V; unused pins may be left open or grounded. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty-Cycle Operation | Enables dropout as low as VOUT + IOUT×(180mΩ + inductor DCR), supporting near-input-output regulation in low-VIN scenarios. |
| Active Output Discharge | Internally discharges SW node when disabled, preventing floating output and ensuring safe power-down sequencing. |
| HICCUP Short-Circuit Protection | Locks out after 32 overcurrent events, then auto-restarts - protects against sustained shorts without latch-up or manual reset. |
| Internal Soft-Start (1ms) | Controls output ramp rate to limit inrush current, preventing input rail collapse and enabling reliable start-up into pre-biased outputs. |
| Thermal Shutdown with Hysteresis | Shuts down at 170°C junction temperature and resumes at 150°C - prevents thermal runaway while allowing recovery without system reset. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62585DRLR | Pin-to-pin compatible; identical SOT-563 package, 1A rating, and 2.4MHz frequency but lacks PG pin and has higher 30µA IQ. | No power-good signaling - unsuitable where rail sequencing or fault monitoring is required. | Select TLV62585DRLR only if PG is unnecessary and lowest BOM cost is prioritized over system-level reliability features. |
| TPS62067DRCR | Same 1A/2.4MHz spec in 3mm × 3mm WSON-8; includes PG, but larger footprint and higher 25µA IQ. | Requires PCB redesign due to different package, pin count, and layout rules; better thermal performance (RθJA = 85°C/W). | Choose TPS62067DRCR when thermal headroom is constrained and board area permits larger package; avoid for strict size-limited designs. |
Compared with TLV62585DRLR and TPS62067DRCR, the TPS62A01DRLR uniquely combines PG functionality, ultra-low 23µA IQ, and minimal 1.6mm × 1.6mm SOT-563 footprint - making it optimal for miniaturized, battery-aware, and sequenced-power systems where both size and supervision matter.

FAQ
What is the maximum output current capability of the TPS62A01DRLR?
The TPS62A01DRLR delivers up to 1A continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN ≥ 3.3V). At ambient temperatures above 85°C or input voltages below 3.3V, thermal derating applies - verified by EVM testing showing potential thermal shutdown at 2A loads. Its 180mΩ/120mΩ HS/LS RDS(on) supports this rating within the SOT-563 thermal limits (RθJA = 157.3°C/W).
Does the TPS62A01DRLR support adjustable output voltage, and how is it set?
Yes, the TPS62A01DRLR supports adjustable output from 0.6V to VIN using an external resistor divider on the FB pin. The nominal feedback voltage is 600mV, so R1 = R2 × (VOUT/0.6 − 1). R2 must not exceed 100kΩ to maintain noise immunity. For example, a 1.8V output uses R2 = 100kΩ and R1 = 200kΩ - matching the typical application circuit shown in the TPS62A01DRLR datasheet.
What is the function of Pin 6 (PG) on the TPS62A01DRLR, and how should it be used?
Pin 6 is the open-drain power-good (PG) output, indicating valid regulation when FB reaches 93.5–96% of target. It requires an external pullup resistor (≤5.5V) and sinks current when active-low. If unused, PG may be left open or tied to GND. The TPS62A01DRLR's PG pin enables safe power sequencing in multi-rail systems - for instance, holding CPU reset until the TPS62A01DRLR output stabilizes - and is absent in non-PG variants like TPS62A01ADRLR.
How does the TPS62A01DRLR manage efficiency at light loads?
The TPS62A01DRLR automatically enters power-save mode (PSM) at light loads, reducing switching frequency and minimizing quiescent current to <23µA. This maintains high efficiency down to 1mA output - critical for always-on functions in battery-powered devices. Unlike forced-PWM variants (e.g., TPS62A01ADRLR), the TPS62A01DRLR's PSM/PWM hybrid operation avoids audible noise and unnecessary switching losses while preserving regulation accuracy.
Is the TPS62A01DRLR pin-compatible with other devices in the same family?
Yes, the TPS62A01DRLR is pin-to-pin compatible with the TLV62585DRLR in the same SOT-563 package, sharing identical pinout, footprint, and basic electrical specs. However, it is not pin-compatible with TPS62A02DRLR (2A) or TPS62A01PDDCR (SOT-23-6), which differ in current rating or package. Always verify thermal and layout requirements - the TPS62A01DRLR's 1.6mm × 1.6mm SOT-563 demands tighter routing than larger packages.
