TB7109F

TOSHIBA BiCD Integrated Circuit Silicon Monolithic

TB7109F

Power supply IC for LNB

The TB7109F is single chip power supply ICs for LNB that integrated

buck DC-DC converter section utilizing a chopper circuit and series

regulator section. The TB7109F contains high-speed P-channel

MOSFETs for the high side main switch to achieve high efficiency. And

series regulator section is fed into a overcurrent circuit of fold buck type,

and it protects this product from the short circuit state of the load.

Features

HSON8-P-0505-1.27

Weight: 0.068 g (typ.)

•

Output current: DC-DC Converter section I_OUT1= 500mA(max.)

Series Regulator section I_OUT2= 400mA(max.)

High efficiency: DC-DC Converter section η = 95% (typ.) (@V_IN1

24V, V_OUT1= 17V, I_OUT1= 300mA)

•

Operating input voltage range: V_IN1= 8V to 27V

On-state resistance: R_DS(ON)= 0.7Ω (high-side) typical (@V_IN1= 24V, Tj = 25℃)

Oscillation frequency: f_OSC= 400kHz (typ.)

Reference voltage: V_REF= 1.215V ± 2.9% (@Tj = 25°C)

Housed in a small surface-mount package (SOP Advance) with a low thermal resistance

Soft-start feature

Overcurrent protection: fold buck type for the Series Regulator section

I_LMIT2(1)= 550mA(typ.)(@ V_IN2= 17V, V_OUT2= 12.5V), I_LMIT2(2)= 100mA(typ.)(@ V_IN2= 17V, V_OUT2= 0V)

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.

The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary

small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily

protect Product under all circumstances. When incorporating Product into your system, please design the system

(1) to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload

conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document

and other documents referenced in this document.
