TK652xx is a low power step-up DC-DC converter designed for portable battery powered systems, capable of operating from a single battery cell down to 0.9 V.
The TK652xx is a low‑power step‑up DC‑DC converter designed for portable, battery‑powered systems. It operates from a single cell down to 0.9 V and delivers regulated output voltages of 1.8 V, 2.1 V or 2.4 V.
Key features include a laser‑trimmed output voltage, low quiescent current, internal band‑gap reference, low output ripple, battery‑monitor indicators (LOI and LBI), and an undervoltage lockout. The device is offered in a miniature SOT‑23L‑6 surface‑mount package and is suited for applications such as cellular phones, pagers, portable instrumentation, and radio‑control systems.
| Supply Voltage Range | 0.90 V – 1.60 V |
|---|---|
| Package Type | SOT‑23L‑6 surface‑mount |
The converter can operate from as low as 0.9 V.
The device is supplied in an SOT‑23L‑6 surface‑mount package.
LBI generates an active‑low signal when the battery voltage falls below 1.1 V.
