Texas Instruments TLV62150ARGTR

Overview

TLV62150ARGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high power density applications. It operates from 4 V to 17 V input, delivers up to 1 A continuous output current, supports adjustable output voltage (0.9 V to 5 V), features DCS-Control™ topology for fast transient response, and integrates Power Good and soft-start functionality - used in mobile PCs, tablets, and POL supplies from Li-ion batteries.

For engineers reviewing the TLV62150ARGTR datasheet, TLV62150ARGTR pinout, TLV62150ARGTR application, or TLV62150ARGTR equivalent, key selection criteria include its 2.5 MHz (or 1.25 MHz) selectable switching frequency, 19 µA quiescent current in Power Save Mode, 100% duty-cycle capability for low-dropout operation, and VQFN-16 (3 mm × 3 mm) package with thermal pad for industrial and portable designs.

Technical Context

The TLV62150ARGTR implements DCS-Control™ topology - a hybrid regulation scheme combining direct output voltage sensing with fast comparator-based timing and a compensated voltage feedback loop. This enables seamless transition between PWM mode (fixed ~2.5 MHz or ~1.25 MHz) and Power Save Mode (frequency scaling with load), while maintaining tight DC regulation and sub-10 mV output ripple under dynamic loads.

It integrates dual MOSFET power switches (90 mΩ high-side, 40 mΩ low-side), programmable soft-start via external capacitor on SS/TR, open-drain Power Good with 92–98% rising threshold, and robust protection including undervoltage lockout (2.7 V ±0.1 V), thermal shutdown (160°C), and cycle-by-cycle current limiting (1.4–1.7 A typical).

FAQ

What is the recommended inductor value for TLV62150ARGTR when operating at 2.5 MHz?

For TLV62150ARGTR operating at 2.5 MHz (FSW=Low), Texas Instruments recommends a 1.0 µH to 1.5 µH shielded power inductor with saturation current ≥1.5 A and DC resistance <50 mΩ. A 1.0 µH, 2.2 A saturation inductor paired with 22 µF X7R ceramic output capacitors achieves optimal balance of size, ripple, and transient response per the typical application schematic in SLVSB71E.

Does TLV62150ARGTR support pre-biased output startup?

Yes, TLV62150ARGTR supports monotonic pre-biased output startup. When enabled into a pre-charged rail, the low-side MOSFET remains off until the internal soft-start ramp exceeds the pre-bias voltage, preventing reverse current flow. This behavior is confirmed in Section 8.3.2 of the SLVSB71E datasheet and requires no external components beyond the standard SS/TR capacitor.

How does the DEF pin affect output voltage accuracy on TLV62150ARGTR?

When DEF=Low, TLV62150ARGTR regulates to nominal output voltage (e.g., 3.3 V set by FB divider); when DEF=High, it increases regulated output by +5% (e.g., 3.465 V). The ±2.5% total accuracy specification applies independently to both states, meaning the +5% margin retains the same absolute tolerance band around the scaled target.

What is the maximum allowable voltage on the PG pin of TLV62150ARGTR?

The PG pin of TLV62150ARGTR is rated for a maximum voltage of 7 V, as specified in Absolute Maximum Ratings (Section 7.1). It must be pulled up to a voltage ≤7 V - typically V_OUT or an auxiliary 3.3 V/5 V rail - and never directly to VIN if VIN exceeds 7 V. Exceeding this rating risks permanent damage to the open-drain structure.

Can TLV62150ARGTR operate with only ceramic output capacitors?

Yes, TLV62150ARGTR is fully compatible with low-ESR ceramic output capacitors only. Its DCS-Control™ architecture is internally compensated for stability with 10 µF to 47 µF X7R/X5R ceramics, eliminating the need for electrolytic or tantalum capacitors. The typical application uses 22 µF, and layout guidelines emphasize short, low-inductance connections to maintain phase margin.
