TF4601

1 MHz Asynchronous Step-up Regulator

White LED Driver

Description

Features

The TF4601 is a monolithic asynchronous boost regulator. An

integrated 500 mW Power MOSFET drives up to 10 WLEDs in se-

ries or up to 13 parallel strings of 3 WLEDs. It operates at ﬁxed

1 MHz switching frequency, maximizing conversion eﬃciency,

enabling smaller external components and reducing output

ripple. The TF4601 features an integrated soft-start function

that minimizes inrush current during turn-on. Under-voltage

lockout, over-voltage and over-temperature protection features

are added for system robustness.

 Drives up to 10 WLEDs in series or up to 13 parallel

strings of 3 WLEDs for display backlighting

 Wide input voltage range: 2.5V to 6V

 High eﬃciency enabled by an integrated 500 mW power

MOSFET switch

 Available with two internal voltage references:

t Version A (104 mV) oﬀers improved eﬃciency

t Version B (300 mV) oﬀers improved accuracy

 Operates at ﬁxed 1 MHz frequency for small ﬁlter size

 1 mA typical shut-down supply current

 Integrated soft-start function, 45V / 20V over-voltage

protection, over-temperature protection and input under-

voltage lockout

The TF4601 is available with two internal voltage references. A

versions with a 104 mV reference oﬀer highest eﬃciency, while

B versions with 300 mV reference oﬀer improved accuracy. The

current mode control loop is compensated internally minimiz-

ing the number of external components.

The TF4601 is oﬀered in space saving 8-pin QFN and 6-pin

TSOT23 packages. It operates over the industrial temperature

range of -40 °C to +85 °C temperature range.

 Industrial temperature range: -40 °C to +85 °C

 Available in space saving QFN-8 and TSOT23-6 packages
