Description

The LM2736YMK/NOPB is Texas Instruments’ compact buck (step-down) DC-DC converter for portable electronics. It integrates a high‑speed switch-mode regulator and power switch to efficiently convert a higher input voltage to a lower, regulated output.
Key points:
- Pb‑free variant: NOPB; package/style identified by YMK.
- Fixed or adjustable output options depending on variant.
- High switching frequency for small external components (inductor and capacitors).
- Requires a few external parts: input/output capacitors, enabling control, and an inductor; a catch diode (or synchronous rectifier) may be used.
- Protection: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown; includes an enable/shutdown control.
- Typical applications: portable/battery-powered devices and other compact, thermally constrained systems.
For exact electrical specs (input range, output voltage, max current, efficiency, pinout, package details), consult the TI LM2736YMK/NOPB datasheet.

Features

Here are the key features of the LM2736YMK/NOPB (TI):
- Buck (step-down) DC-DC converter with internal switching element
- Input voltage range: around 2.7V to 5.5V (suitable for 3V battery systems)
- Output: fixed 3.3V version available; adjustable output versions via external feedback resistors
- Output current: typically up to ~2 A (depends on package and conditions)
- Switching frequency: about 1 MHz (typical)
- High efficiency (up to ~90–95% under suitable conditions)
- Features: enable/shutdown input, soft-start, current limit, and thermal shutdown
- External components: requires inductor and external Schottky catch diode (not a synchronous design)
- Protection: undervoltage lockout, overcurrent protection, thermal protection
- Package: Pb-free (NOPB) MSOP-8 family (YMK variant indicates specific package/revision)
- Applications: portable/low-power systems, cameras, handhelds, accessories
Note: exact current rating and available fixed/adjustable options may vary by specific part revision within the LM2736 family.

Package

SOT-23-5 (5-pin) package.

Pinout

- Pin count: 5 pins (SOT-23-5 package)
- Function: Buck (step-down) switching DC-DC regulator with an integrated high-side switch. Uses external feedback resistors to set Vout and an enable pin for on/off control (pins typically VIN, GND, SW, FB, EN).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits, including power management ICs. It is one of the world's largest semiconductor manufacturers.

Application

Applications: portable and battery-powered electronics needing efficient buck regulation; consumer electronics (set-top boxes, DVD/Blu-ray players, cameras, handheld devices); distributed power rails for microprocessors, FPGAs, and other digital ICs; automotive and industrial equipment requiring compact, low-noise DC-DC conversion; and adapters/power supplies in compact form factors.
