MAX8727ETB

The MAX8727ETB is designed as the high-performance step-up DC-DC converter that belongs to the MAX8727 family which can be used in (1)notebook computer displays; (2)LCD monitor panels. This MAX8727ETB provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). And it also incorporates currentmode, fixed-frequency, pulse-width modulation (PWM) circuitry with a built-in n-channel power MOSFET to achieve high efficiency and fast transient response.

Features of the MAX8727ETB are:(1)90% efficiency; (2)adjustable output from VIN to 24V; (3)2.6V to 5.5V input supply range; (4)input supply undervoltage lockout; (5)pin-programmable 640kHz/1.2MHz switching frequency; (6)programmable soft-start; (7)0.1uA shutdown current; (8)small 10-pin thin DFN package.

The absolute maximum ratings of the MAX8727ETB can be summarized as:(1)lead temperature (soldering, 10s): +300°C;(2)storage temperature range: -65°C to +160°C;(3)junction temperature: +150°C;(4)operating temperature range: -40°C to +85°C;(5)continuous power dissipation (TA=+70°C) 10-pin thin DFN (derate 24.4mW/°C above +70°C): 1951 mW;(6)LX switch maximum continuous RMS current:2.4 A;(7)COMP, SS to GND:-0.3V to VIN+0.3V.
